Abstract

Abstract A novel method for cyanation of aryl halides using formamide as a non-toxic cyanide source is reported. It is a single-step, solvent-free method wherein formamide itself acts as solvent as well as source of cyanide in the presence of phosphorus oxychloride and palladium acetate/xantphos catalyst. Aryl iodides as well as aryl bromides provided moderate to excellent yields of up to 93%.
