As a kind of organotin oxo cluster, the tetraorganodistannoxane[XR 2SnOSnR 2X] 2(Ⅰ,X=Cl,OH,NCS) are useful catalysts for transesterification, esterification, acetallization of carbonyls, ring opening polymerization etc. They show excellent activity in many organic synthetic reactions because of their ladder dimeric structure. Tetraorganodistannoxane catalyzed reaction and corresponding mechanisms are reviewed with 24 references.
