Synthesis of Novel Benzimidazolium Salts of Biologically Active Chalcogenylacetic Acids

摘要

Novel potentially biologically active benzimidazolium-based salts, some of them being ionic liquids, were synthesized by the reaction between substituted benzimidazoles and biologically active acetic acid derivatives RYCH 2CO 2H (R = Ar, 3-indolyl; Y = O, S).
