Palladium N-heterocyclic carbene catalyzed regioselective C-H halogenation of 1-aryl-3-methyl-1H-pyrazol-5(4H)-ones using N-halosuccinimides (NXS)

A novel palladium N-heterocyclic carbene [Pd(NHC)Cl2] complex of vitamin B1 was synthesized and characterized by 1H NMR, EDX, FT-IR and UV-visible spectroscopy. The complex was used as a catalyst for regioselective ortho-C-H chlorination/bromination of 1-aryl-3-methyl-1H-pyrazol-5(4H)-ones via C-H bond activation utilizing Ag2O as the effective terminal additive. The catalyst was easy to prepare, efficient and found to be highly regioselective, affording the target products in moderate to excellent yields.
