Negatively substituted halomethanes were allylated easily by allyltin compounds via radical chain reaction involving SH′ process. Aryl, aralkyl, and alkyl halides underwent similar chain reactions only when the tin compound was charged in excessive amounts.
负取代的卤代
甲烷很容易被烯丙基
锡化合物通过涉及 SH' 过程的自由基链反应进行烯丙基化。只有当
锡化合物加入过量时,芳基、芳烷基和烷基卤才会经历类似的链式反应。
