Mono Arylation of Imidazo[1,2-a]pyridine and 1,2-dimethyl Imidazole: Application of Carbon Nitride Supported Palladium Catalyst

Carbon nitride (gCN) supported nanosized metallic palladium has been prepared, characterized (by various spectroscopic and microscopic techniques) and applied as a catalyst for the mono-arylation of imidazole moieties with broader range of substrates scope. Scaling up of the reaction and recyclability of the catalyst (for 6 cycles) also has been performed for this study. Nitroarene derivatives, produced from the above coupling reaction, could be converted to the corresponding amine derivatives using the same catalyst under mild reaction condition.
