3,3-Difluoroallyltrimethyltin was prepared by reaction of chlorodifluoromethane with the ylide reagent Ph3PCHCH2SnMe3 gem-Difluoroallyllithium, which was generated by the reaction of n-butyllithium with 3,3-difluoroallyltrimethyltin in THF at −95°, was of very limited stability at that temperature. However, in situ procedures and alternate incremental addition procedures allowed its application in
3,3- Difluoroallyltrimethyltin通过用氯二氟甲烷的反应制备内鎓盐试剂博士3 PCHCH 2 SnMe 3宝石Difluoroallyllithium,这是由正丁基锂与THF中的3,3- difluoroallyltrimethyltin的反应在-95产生°,在那个温度下的稳定性非常有限。然而,原位程序和交替的增量添加程序允许其应用于由氯硅烷合成1,1-二氟烯丙基硅烷和由3-戊酮合成CH 2 = CHCF 2 C(OH)-Et 2的应用。
