A number of allylic, allenylic and 2-propynylic (R′) derivatives of tin of the type R3SnR′ have been synthesized, and shown to undergo ready insertion of sulfur dioxide into the SnR′ bond. Rearrangement accompanies insertion so that the products have the alternate allylic, 2-propynylic and allenylic structures respectively. Di-insertion occurs only when groups attached to tin are quite susceptible
已经合成了许多类型为R 3 SnR'的锡的烯丙基,烯丙基和2-丙烯基(R')衍生物,并显示它们易于将二氧化硫插入SnR'键中。重排伴随插入,使得产物分别具有交替的烯丙基,2-丙炔基和烯基结构。仅当与锡连接的基团非常容易发生亲电裂解时,才会发生双插入。报告了化合物的NMR数据。
