描述了甲醇三丁基锡和氧化生物三丁基锡向以下受体分子的加成：异硫氰酸酯、三氯乙腈、二硫化碳、二氧化碳、二氧化硫和碳二亚胺。相应的酚盐通常比甲醇盐的反应性低。初始产物始终是1:1加合物，但在双三丁基锡氧化物与异硫氰酸酯和二硫化碳的反应中，最终产物的性质由二三丁基锡硫化物的消除决定。许多加合物在加热时会解离。许多有机锡化合物非常容易与质子试剂反应，因此有机锡化合物催化醇或水加成至碳二亚胺。
The addition of tributyltin methoxide and of biotributyltin oxide to the following acceptor molecules is described : isothiocyanates, trichloroacetonitrile, carbon disulphide, carbon dioxide, sulphur dioxide, and carbodi-imides. The corresponding phenoxide is generally less reactive than the methoxide. The initial product is always a 1 : 1 adduct, but in the reaction of bistributyltin oxide with isothiocyanates and with carbon disulphide, the nature of the ultimate product is determined by the elimination of bistributyltin sulphide. Many of the adducts dissociate when heated. Many react very readily with protic reagents, and consequently organotin compounds catalyse the addition of alcohols or of water to carbodi-imides.
