complex. When a cyclobutanone bearing a hydrogen atom at the 3-position was used, appropriate choice of the catalyst system led to the selective formation of either a cyclopropane or an alkene. Breaking of the carbon−carbon bond was next combined with hydrogenolysis. When cyclobutanone was treated under hydrogen pressure with a catalytic amount of a rhodium(I) complex having a bidentate diphos...

环丁酮时发生脱羰,得到相应的
环丙烷。
环丙烷的形成表明,Rh(I) 在初始步骤中插入了羰基碳和 α-碳之间的键。还实现了
环丁酮的催化脱羰。反应的模式和速率很大程度上取决于
