Yu, Dan published the artcileCuO nanoparticle-catalyzed diaminations for synthesis of benzimidazole derivatives, Name: 1,2-Diphenyl-1H-benzo[d]imidazole, the publication is Applied Organometallic Chemistry (2016), 30(8), 695-698, database is CAplus.
Copper oxide nanoparticles were applied as an efficient catalyst for the formation of C-N bonds. They can catalyze diaminations for the regiospecific synthesis of 1,2-disubstituted benzimidazoles from 1,2-dihaloarenes and N-arylamidines. The best performance was achieved using CuO nanoparticles with average diameter of 6.5 nm. In addition, the catalyst can be recycled and reused without any significant decrease in catalytic activity.
Applied Organometallic Chemistry 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 C9H5ClO2, Name: 1,2-Diphenyl-1H-benzo[d]imidazole.
