Transition metal-catalyzed reactivity of carbenes with boronic acid derivatives for arylation (alkylation) and beyond

Abstract

This comprehensive review article discussed the reactivity of carbenes with boronic acid derivatives for the one-pot synthesis of diarylmethanes, difluoromethylated arenes, aryl, alkyl boron compounds, arylacetic acid derivatives, furan derivatives,...

Light-induced arylation (alkylation) of N-sulfonylhydrazones with boronic acids

“…4 Later, many groups expanded this chemistry with different transition-metal catalysts under the thermally induced transformation of different carbene sources with boronic acid derivatives. 5 Similarly, Barluenga and Valdés's group reported the reaction of boronic acid derivatives with carbenes, which are derived from N -sulfonylhydrazones. 6 Many groups expanded this chemistry for C–C and C–B bond formations 7 and related compounds 8 with or without using any transition-metal catalyst (Scheme 1a).…”

Visible-Light-Induced Siloxycarbene Addition to N═N of Azodicarboxylates: Synthesis of Acyl Hydrazides from Acylsilanes

“…Carbenes are versatile synthetic intermediates in organic chemistry for C–C, C–heteroatom bond formation, etc., and for the construction of different carbocyclic and heterocyclic compounds in a single step. − Addition of carbenes including metallo carbenes to NN bonds is a reaction that is scantily addressed in the literature. In 1977, Stang’s group reported that the vinyl carbenes derived from vinyl triflate add to azoarenes to yield 2-indazoles .…”
