有机锡化合物在化学工业中作为PVC稳定剂、聚氨酯泡沫形成剂和抗真菌剂而最为人所知。然而，几十年来，它们也被广泛用于硅工业中用于固化有机硅聚合物，尽管事实上，硅氧烷键形成的机制及其固有毒性都没有完全理解。本文综述了有机锡化合物与有机或无机聚合物交联制备各种含聚硅氧烷材料的研究进展。由于它们是该应用的常见成分，因此给出了相关含硅化合物的制备以及它们的反应性的简要概述。此外，由于有一些证据表明，在反应过程中原位形成的stannasiloxanes在反应机理中起着决定性的作用，作为中间体的Sn-O-Si-含化合物的合成和反应性的概述。版权所有（C）2012约翰威利父子有限公司
Organotin compounds are best known in the chemical industry as PVC stabilizers, polyurethane foam formers and antifungal agents. However, they have also been widely used in the silicon industry for decades for curing organosilicon polymers, despite the fact that neither the mechanism through which the siloxane bonds are formed nor their inherent toxicity are completely understood. This review gives an account of the use of organotin compounds in the preparation of diverse polysiloxane-containing materials via cross-linking with either organic or inorganic polymers. As they are common ingredients for this application, a brief outline of the preparation of relevant silicon-containing compounds, as well as their reactivity, are given. In addition, since there is some evidence that stannasiloxanes formed in situ during the reaction play a determinant role as intermediates in the reaction mechanism, an overview of the synthesis and reactivity of Sn-O-Si-containing compounds is also presented.
