Abstract
The achievement of directly activating and utilizing bulk small molecules has remained a longstanding objective in the field of chemical synthesis. The present work reports a catalytic activation method for bulk chemical nitromethane (MeNO2 ). This method combines homogeneous Lewis acid with recyclable heterogeneous Brønsted acid catalysis, featuring practicality, sustainability, and low cost, thus solving the inherent drawbacks of previous Nef processes where stoichiometric reductants or activators were required. By combining the advantages of both homo- and heterogeneous catalysts, this chemistry may not only offer new opportunities for the further development of MeNO2 as a nitrogen source for organic synthesis, but also promote the catalysis design in synthetic chemistry.

Abstract
A synthetic method for the reductive transformation of nitroarenes into ortho-aminated and -annulated products is reported. The method operates via the exhaustive deoxygenation of nitroarenes by an organophosphorus catalyst and a mild terminal reductant to access aryl nitrenes, which after ring expansion, are trapped by amine nucleophiles to give dearomatized 2-amino-3H-azepines. Treatment of these ring-expanded intermediates with acyl electrophiles triggers 6π electrocyclization to extrude the nitrogen atom and restore aromaticity of the phenyl ring, which delivers via C-H functionalization 2-aminoanilide and benzimidazole products.

Abstract
An organophosphorus-catalyzed C-N bond-forming reductive coupling of nitroalkanes with arylboronic acids and esters is reported. The method shows excellent chemoselectivity for the nitro/boronic acid substrate pair, allowing the synthesis of N-(hetero)arylamines rich in functionalization. The identification of a sterically reduced phosphetane catalyst capable of productive coupling in the P(III)/P(V)═O redox manifold is the key enabling development. Combined experimental kinetics and computational mechanistic studies show that the sterically reduced catalyst affects post-rate-limiting steps to enable the C-N coupling event in preference to deleterious side-paths.

Abstract
The direct reductive N-arylation of nitromethane by organophosphorus-catalyzed reductive C-N coupling with arylboronic acid derivatives is reported. This method operates by the action of a small ring organophosphorus-based catalyst (1,2,2,3,4,4-hexamethylphosphetane P-oxide) together with a mild terminal reductant hydrosilane to drive the selective installation of the methylamino group to (hetero)aromatic boronic acids and esters. This method also provides for a unified synthetic approach to isotopically labeled N-methylanilines from various stable isotopologues of nitromethane (i.e., CD3NO2, CH315NO2, and 13CH3NO2), revealing this easy-to-handle compound as a versatile precursor for the direct installation of the methylamino group.

Abstract
![]()
Experimental,
spectroscopic, and computational studies are reported
that provide an evidence-based mechanistic description of an intermolecular
reductive C–N coupling of nitroarenes and arylboronic acids
catalyzed by a redox-active main-group catalyst (1,2,2,3,4,4-hexamethylphosphetane P-oxide, i.e., 1·[O]). The central observations
include the following: (1) catalytic reduction of 1·[O]
to PIII phosphetane 1 is kinetically fast
under conditions of catalysis; (2) phosphetane 1 represents
the catalytic resting state as observed by 31P NMR spectroscopy;
(3) there are no long-lived nitroarene partial-reduction intermediates
observable by 15N NMR spectroscopy; (4) the reaction is
sensitive to solvent dielectric, performing best in moderately polar
solvents (viz. cyclopentylmethyl ether); and (5) the reaction is largely
insensitive with respect to common hydrosilane reductants. On the
basis of the foregoing studies, new modified catalytic conditions
are described that expand the reaction scope and provide for mild
temperatures (T ≥ 60 °C), low catalyst
loadings (≥2 mol%), and innocuous terminal reductants (polymethylhydrosiloxane).
DFT calculations define a two-stage deoxygenation sequence for the
reductive C–N coupling. The initial deoxygenation involves
a rate-determining step that consists of a (3+1) cheletropic addition
between the nitroarene substrate and phosphetane 1; energy
decomposition techniques highlight the biphilic character of the phosphetane
in this step. Although kinetically invisible, the second deoxygenation
stage is implicated as the critical C–N product-forming event,
in which a postulated oxazaphosphirane intermediate is diverted from
arylnitrene dissociation toward heterolytic ring opening with the
arylboronic acid; the resulting dipolar intermediate evolves by antiperiplanar
1,2-migration of the organoboron residue to nitrogen, resulting in
displacement of 1·[O] and formation of the target
C–N coupling product upon in situ hydrolysis.
The method thus described constitutes a mechanistically well-defined
and operationally robust main-group complement to the current workhorse
transition-metal-based methods for catalytic intermolecular C–N
coupling.

Abstract
An organocatalytic method for the modular synthesis of diverse N-aryl and N-alkyl azaheterocycles (indoles, oxindoles, benzimidazoles, and quinoxalinediones) is reported. The method employs a small-ring organophosphorus-based catalyst (1,2,2,3,4,4-hexamethylphosphetane P-oxide) and a hydrosilane reductant to drive the conversion of ortho-functionalized nitroarenes into azaheterocycles through sequential intermolecular reductive C-N cross coupling with boronic acids, followed by intramolecular cyclization. This method enables the rapid construction of azaheterocycles from readily available building blocks, including a regiospecific approach to N-substituted benzimidazoles and quinoxalinediones.
