Hexa-Fe(III) Carboxylate Complexes Facilitate Aerobic Hydrocarbon Oxidative Functionalization: Rh Catalyzed Oxidative Coupling of Benzene and Ethylene to Form Styrene. ACS Catal 2024; 14:10295-10316. [PMID: 38988649 PMCID: PMC11232027 DOI: 10.1021/acscatal.4c02355] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/21/2024] [Revised: 06/04/2024] [Accepted: 06/05/2024] [Indexed: 07/12/2024]
Abstract
Fe(II) carboxylates react with dioxygen and carboxylic acid to form Fe6(μ-OH)2(μ3-O)2(μ-X)12(HX)2 (X = acetate or pivalate), which is an active oxidant for Rh-catalyzed arene alkenylation. Heating (150-200 °C) the catalyst precursor [(η2-C2H4)2Rh(μ-OAc)]2 with ethylene, benzene, Fe(II) carboxylate, and dioxygen yields styrene >30-fold faster than the reaction with dioxygen in the absence of the Fe(II) carboxylate additive. It is also demonstrated that Fe6(μ-OH)2(μ3-O)2(μ-X)12(HX)2 is an active oxidant under anaerobic conditions, and the reduced material can be reoxidized to Fe6(μ-OH)2(μ3-O)2(μ-X)12(HX)2 by dioxygen. At optimized conditions, a turnover frequency of ∼0.2 s-1 is achieved. Unlike analogous reactions with Cu(II) carboxylate oxidants, which undergo stoichiometric Cu(II)-mediated production of phenyl esters (e.g., phenyl acetate) as side products at temperatures ≥150 °C, no phenyl ester side product is observed when Fe carboxylate additives are used. Kinetic isotope effect experiments using C6H6 and C6D6 give k H/k D = 3.5(3), while the use of protio or monodeutero pivalic acid reveals a small KIE with k H/k D = 1.19(2). First-order dependencies on Fe(II) carboxylate and dioxygen concentration are observed in addition to complicated kinetic dependencies on the concentration of carboxylic acid and ethylene, both of which inhibit the reaction rate at a high concentration. Mechanistic studies are consistent with irreversible benzene C-H activation, ethylene insertion into the formed Rh-Ph bond, β-hydride elimination, and reaction of Rh-H with Fe6(μ-OH)2(μ3-O)2(μ-X)12(HX)2 to regenerate a Rh-carboxylate complex.

Abstract
The development and transformation of biomass-derived platform compounds is a sustainable way to deal with the fossil fuel crisis. 5-Hydroxymethylfurfural (HMF) can be reduced or oxidized to produce many high-value compounds; however, it is challenging to effectively produce 2,5-diformylfuran (DFF) due to overoxidation. In this work, a carbon-doped V2O5 (C-V2O5) material was obtained through pyrolysis of MIL-47(V) nanorods, a typical metal-organic framework material. The X-ray diffraction patterns and X-ray photoelectron spectra showed that the graphitized carbon species were incorporated in C-V2O5. High-efficiency HMF oxidation, high specific selectivity for DFF and excellent recycling could be achieved with the C-V2O5 catalyst. Fourier-transform infrared spectroscopy combined with density functional theory (DFT) calculation revealed that graphitized carbon weakens the VO bond and promotes the formation of oxygen vacancies in C-V2O5, thus improving the catalytic activity in the oxidation of furfuryl alcohols. The V4+ induced by oxygen vacancies will be oxidized by O2 to form V5+, so that the cycle can be realized. It exhibits remarkable selectivity in the oxidation of different alcohols produced from biomass based on the relatively constant active sites in C-V2O5.

Abstract
Polyoxometalate nanoparticles were synthesized via a concise solid-state reaction method by directly grinding silver nitrate and the polyoxometalate (NH4)5H6PMo4V8O40 at room temperature without the assistance of a surfactant. The as-prepared Ag6(NH4)5PMo4V8O40 (AgPMo4V8) comprised uniform nanoparticles of 50 nm size, which provided significant catalytic oxidative desulfurization (CODS) performance using O2, N2 + O2 or air as an oxidant. The high efficiency of 100% removal was obtained using AgPMo4V8 nanoparticles as a catalyst in treating model refractory sulfurs. The coexistence of Ag+ and PMo4V8O4011- was the main contribution for this CODS procedure, and the Ag+ species was employed as the electron transfer mediator (ETM) and the PMo4V8O4011- anion was used as the electron donor. The internal electron transfer between Ag+/Ag0 and V5+/V4+ allowed AgPMo4V8 to mimic oxygenase to release the activation energy of oxygen. AgPMo4V8 nanoparticles also exhibited potential for practical catalytic application in the CODS of diesel and gasoline to produce ultra-clean oils with a S content lower than 10 ppm under mild reaction conditions using a mixture of N2 and O2, thus favoring industrial application.

Abstract
Herein we report the first FeII -catalyzed aerobic biomimetic oxidation of amines. This oxidation reaction involves several electron transfer steps and is inspired by biological oxidation in the respiratory chain. The electron transfer from the amine to molecular oxygen is aided by two coupled catalytic redox systems, which lower the energy barrier and improve the selectivity of the oxidation reaction. An iron hydrogen transfer complex was utilized as the substrate-selective dehydrogenation catalyst along with a bifunctional hydroquinone/cobalt Schiff base complex as a hybrid electron transfer mediator. Various primary and secondary amines were oxidized in air to their corresponding aldimines or ketimines in good to excellent yield.

Abstract
We report the first FeII -catalyzed biomimetic aerobic oxidation of alcohols. The principle of this oxidation, which involves several electron-transfer steps, is reminiscent of biological oxidation in the respiratory chain. The electron transfer from the alcohol to molecular oxygen occurs with the aid of three coupled catalytic redox systems, leading to a low-energy pathway. An iron transfer-hydrogenation complex was utilized as a substrate-selective dehydrogenation catalyst, along with an electron-rich quinone and an oxygen-activating Co(salen)-type complex as electron-transfer mediators. Various primary and secondary alcohols were oxidized in air to the corresponding aldehydes or ketones with this method in good to excellent yields.

Abstract
![]()
An efficient Pd/ETM
(ETM = electron transfer mediator)-cocatalyzed
stereoselective oxidative carbocyclization of dienallenes under aerobic
oxidation conditions has been developed to afford six-membered heterocycles.
The use of a bifunctional cobalt complex [Co(salophen)-HQ] as hybrid
ETM gave a faster aerobic oxidation than the use of separated ETMs,
indicating that intramolecular electron transfer between the hydroquinone
unit and the oxidized metal macrocycle occurs. In this way, a class
of important cis-1,4-disubstituted six-membered heterocycles,
including dihydropyran and tetrahydropyridine derivatives were obtained
in high diastereoselectivity with good functional group compatibility.
The experimental and computational (DFT) studies reveal that the pendent
olefin does not only act as an indispensable element for the initial
allene attack involving allenic C(sp3)–H
bond cleavage, but it also induces a face-selective reaction of the
olefin of the allylic group, leading to a highly diastereoselective
formation of the product. Finally, the deuterium kinetic isotope effects
measured suggest that the initial allenic C(sp3)–H bond cleavage is the rate-limiting step, which
was supported by DFT calculations.

Abstract
Guanidino-functionalized aromatics (GFAs) are readily available, stable organic redox-active compounds. In this work we apply one particular GFA compound, 1,2,4,5-tetrakis(tetramethylguanidino)benzene, in its oxidized form in a variety of oxidation/oxidative coupling reactions to demonstrate the scope of its proton-coupled electron transfer (PCET) reactivity. Addition of an excess of acid boosts its oxidation power, enabling the oxidative coupling of substrates with redox potentials of at least +0.77 V vs. Fc+ /Fc. The green recyclability by catalytic re-oxidation with dioxygen is also shown. Finally, a direct comparison indicates that GFAs are real alternatives to toxic halo- or cyano-substituted benzoquinones.

Abstract
In the presence of manganese oxide octahedral molecular sieve (OMS-2) supported copper hydroxide Cu(OH)x/OMS-2, aerobic synthesis of benzoxazoles from catechols and amines via domino oxidation/cyclization at room temperature is achieved. This heterogeneous benzoxazoles synthesis initiated by the efficient oxidation of catechols over Cu(OH)x/OMS-2 tolerates a variety of substrates, especially amines containing sensitive groups (hydroxyl, cyano, amino, vinyl, ethynyl, ester, and even acetyl groups) and heterocycles, which affords functionalized benzoxazoles in good to excellent yields by employing low catalyst loading (2 mol % Cu). The characterization and plausible catalytic mechanism of Cu(OH)x/OMS-2 are described. The notable features of our catalytic protocol such as the use of air as the benign oxidant and EtOH as the solvent, mild conditions, ease of product separation, being scalable up to the gram level, and superior reusability of catalyst (up to 10 cycles) make it more practical and environmentally friendly for organic synthesis.

Abstract
![]()
Herein
we report an example of tandem oxidative acetoxylation/carbocyclization
of arylallenes 1 using Pd(OAc)2. The catalytic
protocol is highly selective and provides access to new C–C
and C–O bonds leading to a carbocyclization. The reaction proceeds
via C–H activation by Pd. Mechanistic investigations show that
the C–H activation is not the rate-limiting step and indicate
that the reaction proceeds via acetoxylation of the allene.

Abstract
A novel protocol for the synthesis of tetrasubstituted olefins through a biomimetic approach has been explored. Both mono- and diarylations were performed under ambient oxygen pressure, giving a range of highly hindered tetrasubstituted alkenes. For diarylation of disubstituted substrates, it was demonstrated that the second arylation is the rate-limiting step of the overall transformation.

Abstract
The room-temperature oxidative C–H/C–H cross-couplings between simple arenes and alkenes, coumarins or quinones have been reported by using a highly electrophilic palladium species [Pd(TFA)2] as the catalyst and cheap (NH4)2S2O8 as the oxidant under air.
