Cobalt Dinitrosoalkane Complexes in the C−H Functionalization of Olefins
摘要:
The use of cobalt dinitrosoalkane complexes in the C-H functionalization of alkenes has been demonstrated. Reaction of a series of alkenes with Me(4)CpCo(CO)(2) in the presence of NO generates intermediate cobalt dinitrosoalkane complexes that can be deprotonated M to the nitrosyl group and added to various Michael acceptors. The resultant products can then undergo retrocycloaddition reactions in the presence of the original alkene to regenerate the starting cobalt dinitrosoalkane complex and release the functionalized alkene.
