Recently NHC-catalyzed radical cross-coupling reactions have sprung up, which provided an efficient method to access ketones from aldehydes or carboxylic acid derivatives with sp3-hybridized carbon radical precursors. It has indirectly solved the limitation of coupling partners scope in NHC umpolung catalysis of aldehydes. In this short review, we present some of the recent advances in NHC-catalyzed radical reactions, with a focus on the construction of C-C(CO) bond.
