Vinylic cyclopropanes were formed highly selectively via the Pd(PPh(3))(4)-catalyzed insertion-intramolecular nucleophilic substitution reaction of aryl or 1-alkenyl iodides with 2-(2', 3'-dienyl)malonates. The regioselectivity observed here is different from what was reported by Cazes et al.
通过钯(三苯基膦)₄催化芳基或1-烯基碘与2-(2',3'-二烯基)丙二酸酯的插入-分子内亲核取代反应,高度选择性地生成了乙烯基环丙烷。此处观察到的区域选择性与卡泽斯等人报道的不同。
