, p. 6483 - 6488 (2012)
A very simple, eco-friendly, and versatile method for the selective synthesis of 1,2-disubstituted benzimidazoles and quinoxalines in water-methanol (1:1) mixture with the aid of resin bound hexafluorophosphate ion as catalyst is reported. The method is also effective for the incorporation of quinoxaline nucleus at the A ring of pentacyclic triterpenoid, friedelin. A plausible mechanism for the formation of disubstituted benzimidazole has also been suggested.

Catalytic role of sodium dodecyl sulfate: Selective synthesis of 1, 2-disubstituted benzimidazoles in water

A simple and efficient procedure for the synthesis of 1, 2-disubstituted benzimidazoles has been developed by a one-pot reaction of o-phenylenediamine with both aromatic and aliphatic aldehydes in the presence of sodium dodecyl sulfate in aqueous medium at room temperature in open air without any organic solvent. The surfactant is recycled. A plausible mechanistic approach has also been suggested.
