Abstract

Abstract : The dinuclear (thio)(silyl)carbene and (seleno)(silyl)carbene gold(i ) complexes 1 and 2 were obtained from the reaction of two equivalents of AuCl(SMe2 ) with the stable bis(methylene)-λ 4 -chalcogenanes 3 and 4, respectively. Abstract : The dinuclear (thio)(silyl)carbene and (seleno)(silyl)carbene gold(i ) complexes 1 and 2 were obtained from the reaction of two equivalents of AuCl(SMe2 ) with the stable bis(methylene)-λ 4 -chalcogenanes 3 and 4, respectively. The reaction proceeds under elimination of the chlorosilane moiety of 3 and 4 . Complexes 1 and 2 were characterized by spectroscopic and X-ray diffraction (XRD) analyses. The 13 C NMR signals for the carbene centers of 1 (309 ppm) and 2 (345 ppm) are by more than 150 ppm downfield shifted relative to those for other known (NHC)AuCl complexes. These results indicate that (chalcogeno)(silyl)carbenes, like (amino)(silyl)carbenes, belong to the push-spectator family of carbenes.
