The use of a catalytic amount of 3-cyanopyridine in the
methyltrioxorhenium catalysed epoxidation of terminal alkenes with aqueous
hydrogen peroxide speeds turnover, which results in the formation of many
functionalized epoxides in high yields.
使用微量的3-
氰基吡啶作为催化剂,在甲基三
氧化铼催化下,以
过氧化氢水溶液作为氧化剂对末端烯烃进行环氧化反应,可以加速反应进程,从而高产率地生成许多功能化的
环氧化物。
