Abstract

The organotin oxo clusters show excellent catalytic activity to many organic synthetic reactions. In this paper, a kind of organotin oxo cluster [Bu₂Sn(OH)OTf]₂ (OTf＝CF₃SO₃) was synthesized by Bu₂SnO and TfOH simply, and the reductions of aldehydes catalyzed by [Bu₂Sn(OH)OTf]₂ were studied. The results showed that [Bu₂Sn(OH)OTf]₂ had excellent activity and selectivity. Only the aldehyde groups could be catalyzed, while the competitive groups such as ketone, ester, alkene, alkyne groups in one molecule or competitive compounds in one reaction system could not be catalyzed.

Key words: organotin oxo cluster, hydrosilylation, selective reduction, aldehyde, selective catalyst
