Three zinc complexes, with the general formula {κ2-C4H3NH[2-CH=NCH2CH2N(CH2CH2)2O]ZnX2} [X = Cl, Br, I], supported by a neutral iminopyrrole-morpholine ligand, were synthesized by the reaction between {C4H3NH-2-[CH=NCH2CH2N (CH2CH2)2O]} and anhydrous zinc dihalides (ZnCl2, ZnBr2, ZnI2) at ambient temperature in dry methanol. The zinc complexes were fully characterized using multinuclear NMR spectroscopic techniques and the mol. structures of complexes in their solid states were determined by single-crystal X-ray diffraction anal. The zinc diiodo complex proved to be a competent precatalyst in the formation of a wide range of benzimidazole and benzothiazole compounds, via aerobic oxidative condensation of several benzylamines with o-phenylenediamine, N-phenyl-o-phenylene-diamine, and o-mercaptoaniline. The benzimidazole and benzothiazole derivatives were successfully characterized using 1H and 13C{1H} NMR spectroscopy.
