2,2-Difluoro-1-arylethenyl diphenyl phosphates, prepared from chloro-difluoromethyl ketones and diphenyl phosphite, reacted with dibutylcopperlithium and successively with various allyl halides to give allylated gem-difluoroolefins in moderate to excellent yields.
由氯代-二氟甲基酮和亚磷酸二苯酯制备的2,2-二氟-1-芳基乙烯基二苯基磷酸酯与二丁基铜锂以及依次与各种烯丙基卤化物反应,以中等至极好的收率得到烯丙基化的宝石-二氟烯烃。
