Dimeric Diorganotin Dications:  Structure and Catalytic Activity in Alcohol Acetylation

Abstract

We report the stabilization of the Sn 2 diorganotin(IV) dication [Ph(L 1 )Sn(μ-OH) 2 Sn(L 1 )Ph] 2+ (1-CB 11 H 12 ) - 2 ( 2 ), where L 1 is 1-{2,6-(MeOCH 2 ) 2 C 6 H 3 }, which in contrast to the rare analogues prepared thus far does not contain a coordinated water molecule. Compound 2 exhibits high catalytic activity in the acetylation of alcohols.
