Among nitrogen-fused azoles, imidazo[1,2-a]pyridines have a main role in the paper because of their wide range of usages in several disciplines like medicinal chemistry, organometallics and material science [1-3]. Herein we wish to investigation the synthesis of 3- iminoaryl-imidazo[1,2-a]pyridines via reaction between numerous aldehydes, trimethylsilyl cyanide and 2-aminopyridine using triphenylammonium tricyanomethanide [Ph3NH][C(CN)3] as a recyclable NMS catalyst under solvent-free condition at 50 oC
