Chakrabarty, Manas published the artcileA mild and expedient one-pot synthesis of substituted benzimidazoles in water using a phase-transfer catalyst, Synthetic Route of 2622-67-5, the publication is Monatshefte fuer Chemie (2009), 140(4), 375-380, database is CAplus.
Substituted benzimidazoles I (R1 = H, Me, i-Pr, Ph; R2 = Ph, 4-MeOC6H4, 2-thienyl, etc.) have been synthesized in very good to excellent yields by a one-pot condensation of phenylenediamines 2-H2NC6H4NHR1 with aryl aldehydes R2CHO in water at room temperature using cetylpyridinium bromide as a cheap and eco-friendly catalyst.
Monatshefte fuer Chemie 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, Synthetic Route of 2622-67-5.
