Controlling the composition and sequence during diazo copolymerization with vinyl or acetylenic monomers is highly desired yet challenging. Here we report a new base-metal-catalysis strategy to address this problem via tandem coupling/polymerization.

A palladium-catalyzed highly regio- and stereoselective allenic C-H oxidative coupling with α-diazo esters is developed. The reaction pathway involves allylic palladium carbene as the key intermediate, which is followed by a carbene migratory insert

Ag(I)-catalyzed synthesis of diazo-trisubstituted furans starting from diazo-cumulated allenyl ketones has been investigated. The Rh2(OAc)4-catalyzed reaction of the diazo 2,3,5-trisubstituted furans provided penta-substituted aromatics via cascade i

A new type of Rh(I)-catalyzed intramolecular [2 + 2 + 1] cycloaddition of diynes and the N-terminal of a diazo moiety is reported. This study is the first attempt to combine oxidative cyclometallation with carbene migratory insertion. This reaction i

Transition-metal-catalyzed cross-coupling reactions through metal carbene migratory insertion have emerged as powerful methodology for carbon–carbon bond constructions. Typically, diazo compounds (or in situ generated diazo compounds from N-tosylhy

Cu(I)-catalyzed reaction of diazo compounds generates a Cu(I)-carbene intermediate that undergoes diverse transformations. In the past few years, the diazo compounds (or their precursor N-tosylhydrazones) have been established as cross-coupling partn

Formal carbene dimerization is a convergent method for the synthesis of alkenes. Herein, we report a Ru(II)-catalyzed carbene dimerization of cyclopropenes and diazo compounds. The yields are up to 97% and the stereoselectivity are up to >20:1. Mecha

A Cu(i)-catalyzed aminoborylation reaction of styrenes is reported. In this transformation, diazo compounds are used as the electrophilic amination agent. The in situ generated benzylcopper species is trapped by the electrophilic nitrogen terminus of

Pd(0)-Catalyzed formal carbene insertion into Si–H bonds has been achieved as an efficient method for C(sp3)–Si bond formation. The reaction, which uses readily available N-tosylhydrazones as the diazo precursors, is highly efficient and shows a
