An efficient visible-light-induced radical carbon oximation of styrenes with 1-nitrosopyrrolidine and organic halides is developed. The reaction proceeds smoothly in the absence a transition metal photocatalyst under mild conditions, producing wide range functionalized oximes moderate to good yields. Mechanistic studies reveal that involves generation nucleophilic α-amino alkyl radicals subsequent halogen atom transfer (XAT) halides.

Nitroso compounds, R-N═O, containing N═O double bonds are ubiquitous and widely utilized in organic synthesis. In contrast, heavier congeners of nitroso namely pnictinidene chalcogenides R-Pn = E (Pn P, As, Sb, Bi; O, S, Se, Te), highly reactive scarce. They have been stabilized the coordination sphere Lewis acid/base or by pronounced contribution from resonance structures, whereas free species with unperturbed pnictogen-chalcogen remains elusive. this work, we report isolation characterization arylstibinidene chalcogenides, which first aromatic compounds. facilely synthesized through salt metathesis reactions aryldichlorostibane dilithium chalcogenides. bear Sb═E (E Se Te) due to poor orbital overlap between C 2p orbitals phenyl ring substituent Sb 5p orbitals. Moreover, they show versatile reactivity, including acting as chalcogen atom transfer reagents reacting small molecules via (cyclo)addition.

We herein introduce an electrochemical route for the N–N bond cleavage of hydrazines. This mild and green methodology utilized readily available mono- 1,1-disubstituted hydrazines or their HCl salts as starting materials to access a broad scope primary secondary amines in high yields. The mechanistic investigation suggests that amine product is formed by consecutive SET reduction, utilization hydrazine salt important providing sufficient conductivity acidity facilitate this reaction.
