of carbenes generated by catalyzed decomposition of diazoesters in the presence of Rh, Pd and Cu catalysts can be controlled to some extent by selecting proper reaction parameters. For a particular diene, the regioselectivity depends both on the catalyst and on the nature of the double-bond (conjugation, substitution).
在Rh,Pd和Cu催化剂存在下,通过重氮催化催化重氮酸酯分解生成的卡宾的环加成反应,多烯环丙烷化的区域选择性可以在一定程度上控制。对于特定的二烯,区域选择性既取决于催化剂又取决于双键的性质(共轭,取代)。
