Abstract

Zwitterionic imidazolium salts bearing 3-sulfonatopropyl, and 2-pyridyl, 2-picolyl, and 2- pyridylethyl substituents have been synthesized and employed as precursors for the preparation of novel water-soluble Au (I)-and Au (III)-NHC complexes of general composition [AuCl (NHC)] and [AuCl3 (NHC)](NHC= N-heterocyclic carbene), respectively. These complexes proved to be active, selective, and recyclable catalysts for the ...
