Abstract

An efficient Pdcatalysed Sonogashira coupling reaction was achieved in the absence of copper and amine with inorganic base using phosphenefree air stable di1Hbenzod123triazol1ylmethane as ligand The cross coupling of electronrich electrondefficient and hindered aryl halides with terminal alkynes afforded the internal alkynes in good to excellent yieldsAn efficient Pdcatalysed Sonogashira coupling reaction was achieved in the absence of copper and amine with inorganic base using phosphenefree air stable di1Hbenzod123triazol1ylmethane as ligand The cross coupling of electronrich electronneutral electrondefficient and hindered aryl halides with terminal alkynes afforded internal arylated alkynes in good to excellent yields
