An Efficient Oxidative Cross-Coupling Reaction between C-H and N-H Bonds; A Transition-Metal-Free Protocol at Room Temperature

A transition-metal-free oxidative coupling of allylic C–H and heterocyclic/aromatic N–H bonds was performed under mild conditions. Promoted by 2,3-dichloro-5,6-dicyano-1,4-benzoquinone (DDQ), up to 99% yield could be achieved.
