Direct one-step synthesis of various benzimidazoles from phenylenediamines and aldehydes is described using air as the oxidant. The salient features of this method include a simple procedure, mild conditions, no coupling agents or commercial oxidants/additives used, no waste produced (only by-product being water), easy purification, and high generality.

Zn3(BTC)2 metal-organic frameworks as recyclable and heterogeneous catalysts were effectively used to catalyze the synthesis of benzimidazole derivatives from o-phenylendiamine and aldehydes in ethanol. This method provides 2-aryl-1H
Copper catalyzed N-arylation of amidines with aryl boronic acids and one-pot synthesis of benzimidazoles by a Chan-Lam-Evans N-arylation and C-H activation/C-N bond forming process

Mono-N-arylation of benzamidines 1 with aryl boronic acids 2 was effectively achieved in the presence of a catalytic amount of Cu(OAc) 2 and NaOPiv under mild aerobic conditions. Combining this step with an intramolecular direct C-H bond functionalization, catalyzed by the same catalytic system but under oxygen at 120 C, afforded benzimidazoles 3 in good to excellent yields.
A simple and efficient one-pot synthesis of 2-substituted benzimidazoles
Bahrami, Kiumars,Khodaei, Mohammad Mehdi,Kavianinia, Iman
, p. 547 - 550 (2008/01/03)
A simple and efficient procedure for the synthesis of substituted benzimidazoles through a one-pot condensation of o-phenylenediamines with aryl aldehydes in the presence of H2O2/HCl system in acetonitrile at room temperature is described. Short reaction time, large-scale synthesis, easy and quick isolation of the products, and excellent yields are the main advantages of this procedure. Georg Thieme Verlag Stuttgart.
