摘要

N-Heterocyclic carbenes (NHCs) are known to be useful ligands for palladium-complex catalysis. It was found that [(NHC) Pd (PPh3) Cl2] is an effective pre-catalyst in Pd-catalyzed C–S cross coupling reactions to produce the functionalized sulfides in excellent yields. The turn over frequency (TOF) for the coupling of p-CH3C6H4Br with p-CH3C6H4SH reaches to 6.25 (mol of product)(mole of catalyst)− 1h− 1.
