lithiation methodology to allylic and benzylic fluorides 1 led to the corresponding allylic and benzylic organolithium reagents, which, in the presence of different electrophiles (Barbier-type reaction conditions), afforded the expected products 2 in moderate yields. The procedure was useful for the transformation of primary, secondary and tertiary benzylic fluorides into the corresponding lithium
萘催化的锂化方法在烯丙基和苄基氟化物1上的应用产生了相应的烯丙基和苄基有机锂试剂,在不同的亲电试剂存在下(Barbier型反应条件),以中等收率提供了预期的产物2。该方法可用于将伯,仲和叔苄基氟化物转化为相应的锂衍生物。当使用两步锂化工艺时(用锂和催化量的萘处理氟化物1,然后添加亲电试剂),仅形成了Wurtz型偶联产物。
