摘要

N-Heterocyclic carbenes (NHCs) derived from imidazolium salts and its derivatives have been widely employed as ligands for the synthesis of a number of NHC–Pd complexes. 1 Subsequently, the catalytic activity of the complexes was examined and some complexes turned out to be better alternative catalysts for the commonly employed phosphine–Pd catalysts. Various monodentate NHC–Pd complexes 1a, 1b, 1c and 1d as well as Pd complexes with two ...
