Electro-sustainable Synthesis: Rapid and Efficient Production of Benzothiazole Derivatives through Electrochemical Means for Sustainable Chemistry

Abstract

Abstract: Electro-organic synthesis suggested a mild, environmentally benign, and atom-efficient pathway to interesting and useful organic compounds. Organic electrochemistry offers an excellent alternative to conventional methods of organic synthesis, avoiding harsh, oxidizing and reducing agents, etc. In our reported work, electro-organic synthesis was carried out in an undivided cell at room temperature in the presence of lithium perchlorate as a supporting electrolyte. Electricity is utilized here instead of a chemical substance with a simple graphite-iron electrode combination. The generation of 2-substituted benzothiazoles was achieved through the amalgamation of bis(2- aminophenyl)disulfides with aromatic aldehydes under the influence of the electrodes. This synthetic process yielded a diverse array of 2-substituted benzothiazoles with satisfactory to excellent yields (64-91%). This is a gentle, sustainable, and metal-free condition for the synthesis of 2-substituted benzothiazoles. In this procedure, subsequent procedural steps encompassed the introduction of distilled water followed by filtration and drying processes to ensure the refinement of the final products.
