    • Because of the possibility of an off-cycle C-H cupration of 1,3-azoles, at the present, we cannot completely exclude an alternative pathway that includes: 1) formation of an arylcopper species through double N,N-N,N-coordination assistance, 2) insertion of the C=N bond of 1,3-azoles into the C-Cu bond, and 3) oxidation leading to rearomatization of azole cores.
