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

Abstract: 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 c… Show more

“…It is worth mentioning that literature reported catalyst systems required the use of more reactive aryl bromides for the preparation of 4 a'', [12] 4 b', [12][13] [6g,h,12-13,15a,16] and 4 l'. However, the steric hindrance from ortho-substituted aryl chloride substrates became significant such that inferior product yields were obtained (68% for 4 b vs. 52% for 4 b' and 75% for 4 e vs. 52% for 4 e').…”

“…The same result was observed when using either 4-iodonitrobenzene or 4-bromonitrobenzene as coupling partners (entries 6 and 7, Table 1). In these cases, the expected product 6 was isolated in 82 and 80% yield 36 , respectively.…”
