摘要

An optimized procedure for the preparation of benzoaza-15-crown-5 is described, and a series of N-substituted derivatives with substituents of various natures have been synthesized. The crystal structure of N-phenylbenzoaza-15-crown-5 was determined by X-ray diffraction. The effect of substituent nature in benzoazacrown ether molecules on its complexation with alkali and alkaline earth metal cations was evaluated by spectrophotometric titration method.
