New [Au(NHC)(OH)] Complexes for Silver-Free Protocols
摘要:
Novel (NHC)gold(I) hydroxides are reported. Their differing tolerances to air and moisture are rationalized by the varying abilities of the NHC ligands to sterically protect the reactive metal center. A number of gold hydroxides were used in the silver-free preparation of Gagosz-type catalysts. This general procedure led to analytically pure products while avoiding the use of expensive silver reagents.

A novel route for the large-scale synthesis of [Au(NHC)(OH)] complexes is reported. Using this new methodology, several [Au(NHC)(OH)] complexes were readily and efficiently accessed on multi-gram scale (up to 20 g). (C) 2014 The Authors. Published by Elsevier Ltd.
