The results of a study of the reactions of HCo(CO)4 and HMn(CO)5 with a variety of a substituted cyclopropenes are consistent with the formation of the intermediate caged radical pairs; recombination in the cage of the radical pair leads to hydroformylation, and cage escape leads to hydrogenation. Steric factors play an important role in determining rates as well as the stereochemistry of the products
对HCo(CO)4和HMn(CO)5与各种取代的环丙烯的反应的研究结果与中间笼形自由基对的形成是一致的。自由基对的笼子中的重组导致加氢甲酰化,而笼子逃逸导致加氢。立体因素在确定速率以及产品的立体化学方面起着重要作用。
