such as O or N undergo only protodestannylation with this electrophile. The reaction of Z-1,2-bis (trimethylstannyl)-1-alkenes with trimethylsilyl chlorosulphonate followed by hydrolysis with aqueous NaHCO3 provides the corresponding sodium sulphonates. SO2 and SO3 undergo insertion into both tin-carbon bonds in an ipso- and stereospecific manner to form bis-sulphinic- or bis-sulphonic bis(trialkylstannyl)
Z -1,2-双(三甲基锡烷基)-1-烯烃对各种亲电子试剂显示出不同类型的反应行为。对甲苯磺酰基异氰酸酯形成五元含锡氮杂环。1,1-二氯甲基甲基醚与碳官能化的二苯乙烯基烯烃反应生成α,β-不饱和醛,这对于合成其他取代的乙烯基锡烷有用。含有诸如O或N的杂原子的Z -1,2-双(三甲基锡烷基)-1-烯烃与该亲电试剂仅进行原脱锡反应。的反应ž -1,2-双(三甲基锡烷基)-1-烯烃与氯磺酸三甲基甲硅烷随后水解用碳酸氢钠水溶液3提供相应的钠磺酸盐。SO 2SO 3和SO 3以ipso-和立体定向方式插入到锡-碳两个键中,以形成双-磺酸-或双-磺酸的双(三烷基锡烷基)酯。

A copper(I)-phosphine complex has been found to facilely promote the distannylation of alkynes with the aid of a base, where a catalytically generated Cu-Sn species serves as a key intermediate. The broad versatility of the copper catalysis has been demonstrated by the facile distannylation of unfunctionalized aliphatic alkynes, being hardly achievable with the conventional palladium catalysts.
