A novel method for the regioselective C2-chlorination of heterocyclic N-oxides has been developed. PPh 3 /Cl 3 CCN were used as chlorinating reagents and the desired N-heterocyclic chlorides were obtained smoothly in satisfactory yields. The reactions proceeded in a highly efficient and selective manner University

A novel cross-dehydrogenative coupling (CDC) of heterocyclic N-oxides with toluene derivatives has been disclosed.
