Abstract
A wide range of internal alkynes are synthesized from the corresponding aryl iodides and terminal alkynes by Sonogashira-type cross-coupling reactions through Caryl-Calkynyl bond formation in the presence of a catalytic amount of readily available DBU-CuBr complex under mild reaction conditions.
Key words
copper catalyst - coupling reaction - arylated alkynes - C-C bond formation - Sonogashira coupling - nitrogen ligands
