Rhodium(III)-catalyzed oxidative coupling of 5-aryl-1H-pyrazoles with alkynes and acrylates.

Xingwei Li1, Miao Zhao.   

Abstract

[RhCp*Cl(2)](2)-catalyzed oxidative coupling of 5-aryl-1H-pyrazoles with alkynes and acrylates has been achieved using Cu(OAc)(2) as an oxidant. Coupling with alkynes afforded six-membered azacycles as a result of C-C and C-N coupling. Coupling with acrylates followed a process of diolefination and a subsequent aza-Michael cyclization.
