摘　　要：烯烃与苯甲酰基亚甲基三苯基胂 (1)反应 ,顺利生成顺 - 1-苯甲酰基 - 2 -芳基取代的环丙烷衍生物。反应不生成反式异构体。副产物三苯基胂可回收。如改用叶立德 (1)对应的溴盐 ,在四氢呋喃或乙腈中于 K2 CO3 存在下反应可获得相同的产物。cis-1-Benzoyl-2-aryl substituted cyclopropane derivatives are prepared from alkene and benzoylmethylenetriphenylarsine(1). No trans isomer is found in the reaction and triphenylarsorane can be recovered as a byproduct. Same result is obtained when corresponding bromide of ylide 1 is used in the presence of K_2CO_3 in tetrahydrofuran or acetonitrile.
