The triorganyl-phosphane/-phosphite-Ni(O) catalyzed [3+2]cycloaddition of methylenecyclopropane (=1) with electron deficient alkenes leads regioselectively to 2,3- or 3,4-disubstituted methylenecyclopentanes depending on the electronic properties of the olefin.
三有机基膦/亚磷酸酯-Ni(O)与缺电子的烯烃催化的亚甲基环丙烷(= 1)的[3 + 2]环加成反应,视区域的电子性质而定,区域选择性地导致2,3-或3,4-二取代的亚甲基环戊烷烯烃。
