Dichloroethenylidenecyclopropanes 4 are obtained in good yields from olefins and tetrachloropropenes 1 and 3 or, more conveniently pentachloropropane 7. The highly reactive allenes 4 readily add nucleophiles (such as methoxide) as well as electrophiles.
从烯烃和四氯丙烯1和3,或更方便地从五氯丙烷7中以高收率获得二氯乙烯亚环丙烷4。高反应性的亚烯4容易添加亲核试剂(例如甲醇盐)以及亲电试剂。
