Abstract: A modified method was proposed to prepare 2-arylbenzimidazoles, 2-(aryl-Y-methyl)benzimidazoles, and some of their 1-ethoxycarbonyl derivatives. The condensation reactions of 2-methylbenzimidazole, 2-(aryloxymethyl)benzimidazole, and 2-(arylthiomethyl)benzimidazole with aromatic aldehydes and phthalic anhydride were also investigated. For series of prepared 2-arylbenzimidazoles the N-H stretching frequencies were correlated with substituent constants of the aryl moiety. The synthesized compounds exhibit moderate growth-stimulating activity on the roots and cotyledons of Zea mays L.
