Abstract
Recent groundbreaking experimental reports demonstrated that Ni complexes bearing a bidentate- or tridentate-bipyridine-based ligand can be used to activate N2O for use as an O-transfer agent in C(sp2)-O bond formation reactions under mild experimental conditions. In this work, quantum chemical calculations are used to shed light on the mechanism through which such metal complexes catalytically activate nitrous oxide, providing new fundamental insights into the development of novel catalysts for N2O revalorization. As a case study, we consider the recent work by Cornella and co-workers (Nature, 2022, 604, 677) concerning the synthesis of phenols from aryl halides at room temperature, which requires the use of an external reducing agent. Our results suggest that the metal center remains in its Ni(II) oxidation state throughout the whole catalytic cycle, despite the presence of various redox steps in the mechanism and the Ni ability to maneuver between a number of oxidation states. This counterintuitive behavior is made possible by the ligand redox activity in the catalytic process, which involves accepting electrons from the reducing agent. Several possible pathways are systematically investigated, each associated with distinct activation modes, kinetics, and reaction outcomes. The governing factors in dictating the preferred path lie in the electronic nature of the ligand (strong vs weak field) and its geometric structure (specifically, the number of coordinating arms). These characteristics play a pivotal role in determining whether the process follows a catalytic or stoichiometric route and can be in principle modulated for the design of new metal complexes with tailored redox properties and reactivity.

Abstract
![]()
Herein we disclose a catalytic synthesis of cycloalkanols
that
harnesses the potential of N2O as an oxygen transfer agent
onto sp3-hybridized carbons. The protocol is distinguished
by its mild conditions and wide substrate scope, thus offering an
opportunity to access carbocyclic compounds from simple precursors
even in an enantioselective manner. Preliminary mechanistic studies
suggest that the oxygen insertion event occurs at an alkylnickel species
and that N2O is the O transfer reagent.

Abstract
The development of catalytic chemical processes that enable the revalorization of nitrous oxide (N2O) is an attractive strategy to alleviate the environmental threat posed by its emissions1–6. Traditionally, N2O has been considered an inert molecule, intractable for organic chemists as an oxidant or O-atom transfer reagent, owing to the harsh conditions required for its activation (>150 °C, 50‒200 bar)7–11. Here we report an insertion of N2O into a Ni‒C bond under mild conditions (room temperature, 1.5–2 bar N2O), thus delivering valuable phenols and releasing benign N2. This fundamentally distinct organometallic C‒O bond-forming step differs from the current strategies based on reductive elimination and enables an alternative catalytic approach for the conversion of aryl halides to phenols. The process was rendered catalytic by means of a bipyridine-based ligands for the Ni centre. The method is robust, mild and highly selective, able to accommodate base-sensitive functionalities as well as permitting phenol synthesis from densely functionalized aryl halides. Although this protocol does not provide a solution to the mitigation of N2O emissions, it represents a reactivity blueprint for the mild revalorization of abundant N2O as an O source. A study demonstrates that nitrous oxide can act as the source of O in a catalytic conversion of aryl halides to phenols, releasing N2 as by-product.

Abstract
Nitrous oxide is a potential diazo transfer reagent, but its applications in organic chemistry are scarce. Here, we show that triazolopyridines and triazoloquinolines are formed in the reactions of metallated 2-alkylpyridines or 2-alkylquinolines with N2O. The reactions can be performed under mild conditions and give synthetically interesting triazoles in moderate to good yields.

Abstract
![]()
Herein
we present the catalytic activation of N2O at
a BiI⇄BiIII redox platform. The activation
of such a kinetically inert molecule was achieved by the use of bismuthinidene
catalysts, aided by HBpin as reducing agent. The protocol features
remarkably mild conditions (25 °C, 1 bar N2O), together
with high turnover numbers (TON, up to 6700) and turnover frequencies
(TOF). Analysis of the elementary steps enabled structural characterization
of catalytically relevant intermediates after O-insertion, namely
a rare arylbismuth oxo dimer and a unique monomeric arylbismuth hydroxide.
This protocol represents a distinctive example of a main-group redox
cycling for the catalytic activation of N2O.

Abstract
The self-assembly process of a cobalt-porphyrin derivative (Co-TCNPP) containing cyanophenyl substituents at all four meso positions on Au(111) was studied by means of scanning tunneling microscopy (STM) and low energy electron diffraction (LEED) under ultrahigh vacuum conditions. Deposition of Co-TCNPP onto Au(111) gave rise to the formation of a close-packed H-bonded network, which was independent of coverage as revealed by STM and LEED. However, a coverage-dependent structural transformation took place upon the deposition of Co atoms. At monolayer coverage, a reticulated long-range ordered network exhibiting a distinct fourfold Co coordination was observed. By reduction of the molecular coverage, a second metal-organic coordination network (MOCN) was formed in coexistence with the fourfold Co-coordinated network, that is, a chevron structure stabilized by a simultaneous expression of H-bonding and threefold Co coordination. We attribute the coverage-dependent structural transformation to the in-plane compression pressure exerted by the molecules deposited on the surface. Our study shows that a subtle interplay between the chemical nature of the building blocks (molecules and metallic atoms) and molecular coverage can steer the formation of structurally different porphyrin-based MOCNs.

Abstract
The one-electron reduction of nitrous oxide (N2 O) was achieved using strong Lewis acids E(C6 F5 )3 (E=B or Al) in combination with metallocenes. In the case of B(C6 F5 )3 , electron transfer to N2 O required a powerful reducing agent such as Cp*2 Co (Cp*=pentamethylcyclopentadienyl). In the presence of Al(C6 F5 )3 , on the other hand, the reactions could be performed with weaker reducing agents such as Cp*2 Fe or Cp2 Fe (Cp=cyclopentadienyl). The Lewis acid-mediated electron transfer from the metallocene to N2 O resulted in cleavage of the N-O bond, generating N2 and the oxyl radical anion [OE(C6 F5 )3 ]⋅- . The latter is highly reactive and engages in C-H activation reactions. It was possible to trap the radical by addition of the Gomberg dimer, which acts as a source of the trityl radical.

Abstract
The divalent cobalt complex of the diprotic pincer ligand bis-pyrazolylpyridine, (H2 L)CoCl2 , is dehydrohalogenated twice by LiN(SiMe3 )2 in the presence of PEt3 to give monomeric S=1/2 LCo(PEt3 )2 (1), fully characterized in the solid-state and solution as a square pyramidal monomer with a long axial Co-P bond. This 17-electron species reacts in time of mixing with N2 O to form L2 Co2 (μ-OPEt3 ) (2)+3 OPEt3 , the former the first example of phosphine oxide bridging two transition metals. The same products are formed from O2 , and divalent cobalt persists even in the presence of excess oxidant. Species (2) catalyzes oxygen atom transfer (OAT) for generation of O=PEt3 from PEt3 from either N2 O or O2 . Bridging and terminal cobalt oxo intermediates are suggested, and the electron donor power, and potential redox activity of the dianionic pincer ligand is emphasized.
