method for the synthesis of 1,1-disubstituted cyclopropanes starting from olefins, acetylenes and AlEt3 in the presence of Cp2ZrCl2, via a step involving in situ formation of aluminacyclopentanes and aluminacyclopentenes, respectively, was developed. Five-membered organoaluminium compounds obtained without preliminary isolation are transformed to cyclopropanes under the effect of Ni(acac)2 in combination
A“一锅”为从烯烃,炔烃及ALET开始1,1-二取代的环丙烷合成方法的催化3在Cp的存在2的ZrCl 2,经由在铝环戊烷和aluminacyclopentenes原位形成涉及的步骤,分别是发达。在氧化铝环戊烷和烷基硫酸盐的实验中,在不经初步分离的情况下获得的五元有机铝化合物在Ni(acac)2的作用下,与烯丙基卤化物一起转化为环丙烷。
