Palladium(II) salts catalyze the Kirmse reaction of allylsulfides with trimethylsilyldiazomethane (TMSD) to give homoallylsulfides. Similarly, TMSD can intercept ArPdX intermediates generated during Stille couplings to give benzhydryl derivatives. The yields of this process are limited by overinsertion and β-elimination. Insertion and elimination can be harnessed to generate styrenes from benzylic
钯(II)盐催化烯丙基硫醚与三甲基甲硅烷基重氮甲烷(TMSD)的Kirmse反应,得到高烯丙基硫醚。类似地,TMSD可以拦截在Stille偶联过程中生成的ArPdX中间体,从而生成二苯甲基衍生物。该过程的产量受到过度插入和β-消除的限制。可以利用插入和消除在钯(0)催化剂存在下从苄基卤化物生成苯乙烯。
