A transition-metal-free strategy for the formation of 1,2-diphenyl-1H-benzo[d]imidazoles from N-phenylbenzimidamides and cyclohexanones is introduced. This is the first report on the direct synthesis of 1,2-diphenyl-1H-benzo[d]imidazoles from cyclohexanones and N-phenylbenzimidamides via iodine promoted oxidative cyclization. Non-aromatic cyclohexanones were smoothly dehydrogenated, and acted as an aryl source using oxygen as a green oxidant. The catalytic use of iodine makes this method quite simple, more economical and convenient. Under optimized conditions, various substituted 1,2-diphenyl-1H-benzo[d]imidazoles were smoothly reacted, and the desired substituted imidazoles were generated in moderate to excellent yields.
Advanced Synthesis & Catalysis published new progress about 2622-67-5. 2622-67-5 belongs to imidazoles-derivatives, auxiliary class Benzimidazole,Benzene,Benzimidazole, name is 1,2-Diphenyl-1H-benzo[d]imidazole, and the molecular formula is C19H14N2, Safety of 1,2-Diphenyl-1H-benzo[d]imidazole.
