已经证明二亚硝基烷烃钴配合物在烯烃的 C-H 官能化中的用途。一系列烯烃与 Me(4)CpCo(CO)(2) 在 NO 存在下反应生成中间体钴二亚硝基烷络合物，该络合物可以将 M 去质子化为亚硝酰基并添加到各种迈克尔受体上。然后所得产物可以在原始烯烃存在下进行逆环加成反应，以再生起始二亚硝基烷钴络合物并释放官能化烯烃。
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.
