Abstract: N-(2-Azidophenyl)azolium salts were easily prepared and reacted with copper(i) under conditions allowing the formation of NHC complexes. Under these conditions, the formation of benzimidazo-fused heterocycles occurred under catalytic, efficient and very mild conditions. This reaction… read more here.

Abstract: A one-pot two-step oxidative process using tert-butyl hydroperoxide (TBHP) mediated transformation of aldehydes and amines into amides catalyzed by Copper (I) - Iodide and N-heterocyclic carbenes is developed. The process utilized is additive-free, which does… read more here.
