Guan, Qianqian published the artcileThe synthesis of benzimidazoles via a recycled palladium catalyzed hydrogen transfer under mild conditions, Safety of 1,2-Diphenyl-1H-benzo[d]imidazole, the publication is Organic & Biomolecular Chemistry (2018), 16(12), 2088-2096, database is CAplus and MEDLINE.
An efficient synthesis of benzimidazoles I [R1 = Me, Ph, 2-thienyl, etc.; R2 = H, Me, CF3; R3 = H, Me, Ph, 2-pyridyl, 3-Me-2-pyridyl] was developed via recycled palladium-catalyzed hydrogen-transfer reaction of N-substituted-2-nitroanilines and alcs. The reaction was carried out smoothly under mild conditions that afforded variety of benzimidazoles I with good to excellent yields. The palladium catalyst was recovered easily and reused six times with great catalytic activity.
