Abstract

Abstract : We report the synthesis, charaterization and catalytic performance of a unique bis(triazolylidene) gold(i ) complex featuring a large [(Tp Me2 )2 K] anion. Abstract : In the quest of heteroleptic gold(i ) complexes containing triazolylidenes (MIC) and Tp Me2 ligands, we discovered that reaction of the MIC–Au–I complex2 with potassium hydrotris-(3, 5-dimethyl-1-pyrazolil) borate (KTp Me2 ) produces an unexpected bis(triazolylidene) gold(i ) complex featuring a large [(Tp Me2 )2 K] anion (3 ). An optimized synthesis was achieved by reacting a preformed bis(triazolylidene)Au(i ) complex (2a ) with two equivalents of KTp Me2 (81%). Full characterization and preliminary catalytic results demonstrate the high performance of complex3 in the formation of several oxazoline derivatives.
