trans-isomer, while cis-and α-products are formed in lower yields. In some cases the stannyl alkenols can be further hydrostannated to give distannyl alkanols. 13C and 119Sn NMR data for the organotin compounds are presented and discussed.
1-炔醇的氢化锡锡以良好的产率导致形成相应的三有机锡烷基烯醇。主要产物是反式异构体,而顺式和α型产物的产率较低。在某些情况下,可以进一步氢化锡烷基醇,以得到二锡烷基醇。给出并讨论了有机锡化合物的13 C和119 Sn NMR数据。

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。
