Abstract

2, 2′-Diamino-6, 6′-dimethylbiphenyl (L1) was found to be a good ligand in the CuI- catalyzed Sonogashira coupling reaction of various aryl iodides and bromides with terminal alkynes. Under suitable conditions, all reactions gave the desired coupling products in moderate to excellent yields.
