摘要
综述了以四烃基二锡氧烷 为代表的有机锡氧簇合物作为催化剂在酯交换、酯化、羰基缩醛保护和脱保护以及开环聚合等有机反应中的催化作用。化合物 的 Sn-O环具有独特的二聚层状结构 ,使其在有机合成中体现出特殊的催化活性。本文就相关反应和反应机理进行了综述。参考文献 2
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.
