摘要:上vinyltriphenylphosnium溴化物phenylithium的作用在形成(c导致两者6 ħ 5)3 P +c-Hch 2 C ^ 6 ħ 5(ca 0.45%)和质子抽象(部分来自乙烯基的α质子),由orgnometallic基地提供.当使用甲基或乙基锂时,获得甚至更低的相应膦亚甲基收率.(β-溴乙基)三苯基phosph溴化物和乙烯-1,2-双(三苯基phosph)二溴化物就地效果很好在这种反应中反应生成乙烯基phosph盐.还实现了将苯基锂类似地添加到溴化1-丙烯基三苯基phosph和溴化(1-甲基-1-丙烯基)三苯基phosph中,但是由于复杂的副反应,收率非常低.有机锂试剂isopropenyltriphenylphosphonium溴化,得到(c 6 H ^ 5)3 P +c-(ch 3)ch 2中的r,产量高.值得注意的是,观测到三苯基膦亚甲基加到溴化异丙烯基三苯乙phosph上.
