Abstract
A copper-catalyzed method for the dehydrogenation of various nitrogen-containing heterocycles to furnish quinolines and indoles has been developed. A range of 1,2,3,4-tetrahydroquinolines underwent dehydrogenation by employing 2 mol % of copper complex Cat 3 as a catalyst and using O2 as an oxidant at 120 °C in 1,2-dichlorobenzene to afford the desired quinolines. The method enables the dehydrogenation of a variety of indolines in the presence of 2 mol % of copper complex Cat 2, using 10 mol % of TEMPO as an additive and O2 as an oxidant under room temperature in tetrahydrofuran to furnish indoles in high yields. Mechanistic studies suggested that the dehydrogenative activity is ascribed to the formation of a copper(II) active species from copper(I) complexes oxidized by O2, which was proved by high-resolution mass spectrometry (HRMS). The copper-catalyzed dehydrogenation reaction proceeds via a superoxide radical anion (·O2-) as proved by electron paramagnetic resonance (EPR) spectrometry. In situ infrared spectroscopy revealed that the dihydroquinoline intermediate was formed in the dehydrogenation of 1,2,3,4-tetrahydroquinolines.

[PMID: 37441048 PMCID: PMC10334261 DOI: 10.1039/d3ra04305c] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/27/2023] [Accepted: 07/04/2023] [Indexed: 07/15/2023] Open
Abstract
The catalytic acceptorless dehydrogenation (ADH) of saturated N-heterocycles has recently gained considerable attention as a promising strategy for hydrogen release from liquid organic hydrogen carriers (LOHCs). Recently, a simple tBuOK base-promoted ADH of N-heterocycles was developed by Yu et al. (Adv. Synth. Catal. 2019, 361, 3958). However, it is still open as to how the tBuOK plays a catalytic role in the ADH process. Herein, our density functional study reveals that the tBuOK catalyzes the ADH of 1,2,3,4-tetrahydroquinoline (THQ) through a quasi-metal-ligand bifunctional catalytic channel or a base-catalyzed pathway with close energy barriers. The hydride transfer in the first dehydrogenation process is determined to be the rate determining step, and the second dehydrogenation can proceed directly from 34DHQ regulated by the tBuOK. In addition, the computational results show that the cooperation of a suitable alkali metal ion with the tBuO- group is so critical that the tBuOLi and the isolated tBuO- are both inferior to tBuOK as a dehydrogenation catalyst.

Abstract
The synthesis of imines denotes a cornerstone in organic chemistry. The use of alcohols as renewable substituents for carbonyl-functionality represents an attractive opportunity. Consequently, carbonyl moieties can be in situ generated from alcohols upon transition-metal catalysis under inert atmosphere. Alternatively, bases can be utilized under aerobic conditions. In this context, we report the synthesis of imines from benzyl alcohols and anilines, promoted by KOt Bu under aerobic conditions at room temperature, in the absence of any transition-metal catalyst. A detailed investigation of the radical mechanism of the underlying reaction is presented. This reveals a complex reaction network fully supporting the experimental findings.

Abstract
We report a convenient protocol for a nitrogen atom insertion into indenes to afford isoquinolines. The reaction uses a combination of commercially available phenyliodine(iii) diacetate (PIDA) and ammonium carbamate as the nitrogen source to furnish a wide range of isoquinolines. Various substitution patterns and commonly used functional groups are well tolerated. The operational simplicity renders this protocol broadly applicable and has been successfully extended towards the direct interconversion of cyclopentadienes into the corresponding pyridines. Furthermore, this strategy enables the facile synthesis of 15N labelled isoquinolines, using 15NH4Cl as a commercial 15N source.

Abstract
Reactions of the hexahydride OsH6(PiPr3)2 (1) with 2-butyne and 3-hexyne and the behavior of the resulting species toward pinacolborane (pinBH) have been investigated in the search for new hydroboration processes. Complex 1 reacts with 2-butyne to give 1-butene and the osmacyclopropene OsH2(η2-C2Me2)(PiPr3)2 (2). In toluene, at 80 °C, the coordinated hydrocarbon isomerizes into a η4-butenediyl form to afford OsH2(η4-CH2CHCHCH2)(PiPr3)2 (3). Isotopic labeling experiments indicate that the isomerization involves Me-to-COs hydrogen 1,2-shifts, which take place through the metal. The reaction of 1 with 3-hexyne gives 1-hexene and OsH2(η2-C2Et2)(PiPr3)2 (4). Similarly to 2, complex 4 evolves to η4-butenediyl derivatives OsH2(η4-CH2CHCHCHEt)(PiPr3)2 (5) and OsH2(η4-MeCHCHCHCHMe)(PiPr3)2 (6). In the presence of pinBH, complex 2 generates 2-pinacolboryl-1-butene and OsH{κ2-H,H-(H2Bpin)}(η2-HBpin)(PiPr3)2 (7). According to the formation of the borylated olefin, complex 2 is a catalyst precursor for the migratory hydroboration of 2-butyne and 3-hexyne to 2-pinacolboryl-1-butene and 4-pinacolboryl-1-hexene. During the hydroboration, complex 7 is the main osmium species. The hexahydride 1 also acts as a catalyst precursor, but it requires an induction period that causes the loss of 2 equiv of alkyne per equiv of osmium.

Abstract
The hexahydride complex OsH6(PiPr3)2 promotes the C-H bond activation of the 1,3-disubstituted phenyl group of the [BF4]- and [BPh4]- salts of the cations 1-(3-(isoquinolin-1-yl)phenyl)-3-methylimidazolium and 1-(3-(isoquinolin-1-yl)phenyl)-3-methylbenzimidazolium. The reactions selectively afford neutral and cationic trihydride-osmium(IV) derivatives bearing κ2-C,N- or κ2-C,C-chelating ligands, a cationic dihydride-osmium(IV) complex stabilized by a κ3-C,C,N-pincer group, and a bimetallic hexahydride formed by two trihydride-osmium(IV) fragments. The metal centers of the hexahydride are separated by a bridging ligand, composed of κ2-C,N- and κ2-C,C-chelating moieties, which allows electronic communication between the metal centers. The wide variety of obtained compounds and the high selectivity observed in their formation is a consequence of the main role of the azolium group during the activation and of the existence of significant differences in behavior between the azolium groups. The azolium role is governed by the anion of the salt, whereas the azolium behavior depends upon its imidazolium or benzimidazolium nature. While [BF4]- inhibits the azolium reactions, [BPh4]- favors the azolium participation in the activation process. In contrast to benzimidazolylidene, the imidazolylidene resulting from the deprotonation of the imidazolium substituent coordinates in an abnormal fashion to direct the phenyl C-H bond activation to the 2-position. The hydride ligands of the cationic dihydride-osmium(IV) pincer complex display intense quantum mechanical exchange coupling. Furthermore, this salt is a red phosphorescent emitter upon photoexcitation and displays a noticeable catalytic activity for the dehydrogenation of 1-phenylethanol to acetophenone and of 1,2-phenylenedimethanol to 1-isobenzofuranone. The bimetallic hexahydride shows catalytic synergism between the metals, in the dehydrogenation of 1,2,3,4-tetrahydroisoquinoline and alcohols.

Abstract
![]()
The reaction of the hexahydride OsH6(PiPr3)2 with a P,Ge,P-germylene-diphosphine
affords
an osmium tetrahydride derivative bearing a Ge,P-chelate, which arises
from the hydrogenolysis of a P–C(sp3) bond. This
Os(IV)–Ge(II) compound is a pioneering example of a bifunctional
catalyst based on the coordination of a σ-donor acid, which
is active in the dehydrogenation of formic acid to H2 and CO2. The kinetics
of the dehydrogenation, the characterization of the resting state
of the catalysis, and DFT calculations point out that the hydrogen
formation (the fast stage) exclusively occurs on the coordination
sphere of the basic metal center, whereas both the metal center and
the σ-donor Lewis acid cooperatively participate in the CO2 release (the rate-determining step). During the process,
the formate group pivots around the germanium to approach its hydrogen
atom to the osmium center, which allows its transfer to the metal
and the CO2 release. An alternative
class of bifunctional catalysts can be assembled
by coordination of σ-donor Lewis acids to platinum-group-metal
basic fragments. In contrast to what happens with the previously reported
bifunctional catalysts, this design allows enhancing the basicity
of the base and the acidity of the acid. According to this, a bifunctional
catalyst for the dehydrogenation of formic acid, based on an osmium(IV)-germylene
cooperative system, has been prepared and the mechanism of the catalysis
established.

proportional to the concentrations of the catalyst precursor, nitrile,
and water. When these experimental findings and density functional
theory calculations are combined, the mechanism of catalysis has been
established. Complexes OsH3{κ2-N,O-[HNC(O)R]}(PiPr3)2 dissociate the carbonyl group of the chelate to afford
κ1-N-amidate derivatives, which
coordinate the nitrile. The subsequent attack of an external water
molecule to both the C(sp) atom of the nitrile and the N atom of the
amidate affords the amide and regenerates the κ1-N-amidate catalysts. The attack is concerted and takes place
through a cyclic six-membered transition state, which involves Cnitrile···O–H···Namidate interactions. Before the attack, the free carbonyl
group of the κ1-N-amidate ligand
fixes the water molecule in the vicinity of the C(sp) atom of the
nitrile. The hexahydride complex OsH6(PiPr3)2 competently catalyzes the
hydration of aliphatic
nitriles to amides. Isolation of the main metal species under the
catalytic conditions, kinetics of hydration, and density functional
theory calculations support an alternative mechanism to those previously
reported.

Abstract
![]()
Rhodium
and iridium diolefin catalysts for the acceptorless and
base-free dehydrogenation of secondary alcohols have been prepared,
and their degradation has been investigated, during the study of the
reactivity of the dimers [M(μ-Cl)(η4-C8H12)]2 (M = Rh (1), Ir
(2)) and [M(μ-OH)(η4-C8H12)]2 (M = Rh (3), Ir (4)) with 1,3-bis(6′-methyl-2′-pyridylimino)isoindoline
(HBMePHI). Complex 1 reacts with HBMePHI, in dichloromethane,
to afford equilibrium mixtures of 1, the mononuclear
derivative RhCl(η4-C8H12){κ1-Npy-(HBMePHI)} (5), and the binuclear species [RhCl(η4-C8H12)]2{μ-Npy,Npy-(HBMePHI)} (6). Under
the same conditions, complex 2 affords the iridium counterparts
IrCl(η4-C8H12){κ1-Npy-(HBMePHI)} (7) and [IrCl(η4-C8H12)]2{μ-Npy,Npy-(HBMePHI)} (8). In contrast to chloride,
one of the hydroxide groups of 3 and 4 promotes
the deprotonation of HBMePHI to give [M(η4-C8H12)]2(μ-OH){μ-Npy,Niso-(BMePHI)} (M = Rh
(9), Ir (10)), which are efficient precatalysts
for the acceptorless and base-free dehydrogenation of secondary alcohols.
In the presence of KOtBu, the [BMePHI]− ligand undergoes three different degradations: alcoholysis
of an exocyclic isoindoline-N double bond, alcoholysis of a pyridyl-N
bond, and opening of the five-membered ring of the isoindoline core.

Abstract
![]()
Reactions of polyhydrides OsH6(PiPr3)2 (1)
and IrH5(PiPr3)2 (2) with rollover cyclometalated
hydride complexes have been investigated in order to explore the influence
of a metal center on the MHn unit of the
other in mixed valence binuclear polyhydrides. Hexahydride 1 activates an ortho-CH bond of the heterocyclic
moiety of the trihydride metal–ligand compounds OsH3{κ2-C,N-[C5RH2N-py]}(PiPr3)2 (R = H (3), Me (4), Ph (5)). Reactions of 3 and 4 lead to the hexahydrides
(PiPr3)2H3Os{μ-[κ2-C,N-[C5RH2N-C5H3N]-N,C-κ2]}OsH3(PiPr3)2 (R = H (6), Me (7)),
whereas 5 gives the pentahydride (PiPr3)2H3Os{μ-[κ2-C,N-[C5H3N-C5(C6H4)H2N]-C,N,C-κ3]}OsH2(PiPr3)2 (8).
Pentahydride 2 promotes C—H bond activation of 3 and the iridium-dihydride IrH2{κ2-C,N-[C5H3N-py]}(PiPr3)2 (9)
to afford the heterobinuclear pentahydride (PiPr3)2H3Os{μ-[κ2-C,N-[C5H3N-C5H3N]-N,C-κ2]}IrH2(PiPr3)2 (10) and the homobinuclear tetrahydride (PiPr3)2H2Ir{μ-[κ2-C,N-[C5H3N-C5H3N]-N,C-κ2]}IrH2(PiPr3)2 (11), respectively. Complexes 6–8 and 11 display HOMO delocalization
throughout the metal–heterocycle-metal skeleton. Their sequential
oxidation generates mono- and diradicals, which exhibit intervalence
charge transfer transitions. This notable ability allows the tuning
of the strength of the hydrogen–hydrogen and metal–hydrogen
interactions within the MHn units. The influence of a metal center on the
MHn unit of the other in binuclear osmium-
and iridium-polyhydride
complexes bearing rollover cyclometalated bipyridines as a bridging
ligand has been studied.

Abstract
The reduction of the N≡C bond of benzonitriles promoted by OsH6(PiPr3)2 (1) has been studied. Complex 1 releases a H2 molecule and coordinates 2,6-dimethylbenzonitrile to afford the tetrahydride OsH4{κ1- N-(N≡CC6H3Me2)}(PiPr3)2 (2), which is thermally stable toward the insertion of the nitrile into one of the Os-H bonds. In contrast to 2,6-dimethylbenzonitrile, benzonitrile and 2-methylbenzonitrile undergo insertion, via Os(η2-N≡CR) intermediates, to give the azavinylidene derivatives OsH3(═N═CC6H4R)(PiPr3)2 [R = H (3) or Me (4)]. The analysis by means of computational tools (EDA-NOCV) of the bonding situation in these compounds suggests that the donor-acceptor nature of the osmium azavinylidene bond dominates over the mixed electron-sharing/donor-acceptor and pure electron-sharing bonding modes. The N atom is strongly nucleophilic, whereas one of the hydrides is electrophilic. In spite of the different nature of these centers, the migration of the latter to the N atom is kinetically prevented. However, the use of water as a proton shuttle allows hydride migration, as a consequence of a significant decrease in the activation barrier. The resulting phenylaldimine intermediates evolve by means of orthometalation to give OsH3{κ2- N, C-(NH═CHC6H3R)}(PiPr3)2 [R = H (5) or Me (6)]. The presence of electrophilic and nucleophilic centers in 3 confers upon it the ability to activate σ-bonds, including H2 and pinacolborane (HBpin). The reaction with the latter gives OsH3{κ2- N, C-[N(Bpin)═CHC6H4]}(PiPr3)2 (7).
