reacted with norbornene in the presence of a catalytic amount of tetrakis(tripheylphosphine)palladium to give cyclopropyl ketones. The reaction proceeded with high stereoselectivity, affording a single stereoisomer. The reaction of various substituted norbornenes gave the corresponding cyclopropanes in moderate to good yields.
乙酸炔丙酯在催化量的四(三苯甲基膦)钯存在下与降冰片烯反应,得到环丙基酮。反应以高的立体选择性进行,得到单一的立体异构体。各种取代的降冰片烯的反应以中等至良好的产率得到了相应的环丙烷。
