We have reported here a new synthetic protocol for the formation of C-N bond catalyzed by a thiosemicarbazone complex of copper. This in situ complex has been found to be very effective for Chan-Lam C-N cross-coupling reaction of anilines and various imidazoles at room temperature. Pyrazole and 4-bromoindole were also activated for C-N bond formation by using this protocol at room temperature. This catalytic system gave good-to-excellent yield using a mixture of DMF and water as solvent in a 1:1 proportion.
