摘要
A new, efficient, and inexpensive CuCl2/salicylic acid catalytic system has been developed to catalyze Sonogashira-type cross-coupling of haloarenes and iodoheteroarenes with terminal alkynes under mild reaction conditions to afford the corresponding coupling products in 18-95% yields. The role of salicylic acid might act as a bidentate O,O-donor ligand to activate the catalytic reactivity of copper chloride in coupling reactions was also briefly discussed. (C) 2010 Elsevier Ltd.
