Abstract

Abstract : A [Ph3 PAu] + η 2 -alkyne π complex is found to be shelf-stable and effective for a range of the Au(i )-catalyzed alkyne π activation reactions. Abstract : A linear η 2 -alkyne π complex of [Ph3 PAu] +, namely Au(i ) π-bis( tert -butyldimethylsilyl)acetylene triphenylphosphine complex (1 ), was prepared and characterized. The new complex is found to be shelf-stable and effective for a range of the Au(i )-catalyzed alkyne π activation reactions, including a glycosylation reaction with glycosyl ortho -alkynylbenzoates as donors.
