The aldimines reacted with alkenes under a rhodium catalytic system, Rh[(coe)2Cl]2 and Cy3P, to give mainly the double alkylated products with moderate to high yields. On the other hand, the ketimine 9 gave the mono alkylated product predominantly.
所述醛亚胺在铑催化体系Rh [(coe)2 Cl] 2和Cy 3 P下与烯烃反应,主要得到中等至高收率的双烷基化产物。另一方面,酮亚胺9主要给出单烷基化产物。
