Radical hydroformylation and hydrogenation of cyclopropenes with HCo(CO) 4 and HMn(CO) 5

Abstract

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.
