摘要:
N-Heterocyclic carbenes (NHCs) are known to be useful ligands for palladium-complex catalysis It was found that [(NHC)Pd(PPh3)Cl-2] 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-CH3C6H4Bi with p-CH3C6H4SH reaches to 6 25 (mol Of product) (mole of catalyst)(-1) h(-1) (C) 2010 Elsevier Ltd All rights reserved
