A simple skeletal editing protocol "inserts" a nitrogen atom into arylcycloalkenes to form the corresponding N-heterocycles. The use of an inexpensive cobalt catalyst under aqueous and open-air conditions makes this protocol very practical. Examples include late-stage modification of compounds of pharmaceutical interest and complex fused ring compounds.
