experimental part, p. 140 - 144 (2009/08/15)
A very simple, mild, and highly efficient green catalyst has been developed for the synthesis of 2-substituted benzimidazoles by treatment of substituted ortho-phenylenediamines and aldehydes in water at 80C in the presence of boric acid (5 mol-%) and glycerol (0.05 mL). This methodology has been standardized on 55 substrates, and nine new compounds have been synthesized.

, (2008/06/13)
Cyclic bis benzimidazole ligands of the following formula are formed by contacting a (2-aminophenyl)-benzimidazole-4-carboxaldehyde ethylene acetal or a (2-nitrophenyl)-benzimidazole-4-benzaldehyde with an acid optionally in the presence of a metal or a metal salt. wherein R1and R2may be the same or different and are selected from H, an alkyl having 1 to 10 carbon atoms, a benzyl group, a substituted 2-ethylphenyl group, a carbonyl group, a phenyl substituent, a tosyl group, and an alkylsulfonate group; R3and R4may be the same or different and are selected from H, methyl, and ethyl; and R5, R6, R7, R8, R9, R10, R11, R12, R13, R14, R15, R16, R17, and R18may be the same or different and are selected from H, alkyl having 1 to 10 carbon atoms, fluoride, chloride, bromide, iodide, nitro, amino, a carboxylate, an ester, and a phenyl group.
