Abstract:The development of convenient and efficient methods for the synthesis of benzothiazoles and benzimidazoles is attracting considerable attention due to their antitumor,anticancer,and antimicrobial activities.Over the past few decades,many methods have been developed for the synthesis of benzothiazoles and benzimidazoles.~1 However,these methods have one or more shortcomings such as microwave radiations,metal catalysts,additives and/or high temperature
