Abstract

A number of benzenesulfonyl derivatives of benzoimidazol-2-ylamine and 1-methyl-benzoimidazol-2-ylamine were synthesized, their synthesis reactions under different experimental conditions being monitored by hptlc. The crystal and molecular structures of N-(1-benzenesulfonyl-1,3-dihydrobenzoimidazol-2-ylidene)benzenesulfonamide (4) and N-(1-benzenesulfonyl-3-methyl-1,3-dihydro-benzoimidazol-2-ylidene)-benzenesulfonamide (7) were determined by X-ray diffraction analysis. The structure of compound 4 is made up of two crystallographically independent molecules and that of compound 7 of one molecule. In both cases, the structure contains the imido form of the molecules. There are strong conjugative effects between the imido groups and the imidazolic rings. Weak intramolecular C-H ... O hydrogen bonding interactions could influence the molecular conformations.
