Abstract
We have developed the first N-heterocyclic carbene (NHC)-based transition metal catalysts for C−S coupling reactions. Ni−NHC catalysts showed good to excellent activities toward various aryl halides in C−S coupling reactions. The catalytic activities were greatly affected by the electronic and steric properties of the NHC ligands. The new catalysts were inexpensive, easy to synthesize, and environmentally friendly. They could be excellent candidates to replace Pd-organophosphanes for C−S coupling catalysis.Keywords
