An Environmental Benign Green Synthetic Approach for Some Benzimidazole Derivatives

Abstract

A green synthetic protocol was developed for the synthesis of various benzimidzole derivatives. Microwaves were used as a tool for safer, cleaner, cheaper and faster reaction products. This technique has emerged as microwave assisted organic synthesis (MAOS) which is superior to various conventional heating procedures. Some benzimidazole derivatives were synthesized simply by irradiating the various combinations of carboxylic acids and 1,2-phenylinediamines under suitable reaction conditions within a shorter period of 15 minutes with 81-85% yield.
