Abstract: A novel protocol, efficient, inexpensive for the microwave-assisted copper-catalyzed synthesis of benzothiazoles derivatives through the reaction of 2-iodoanilines with aldehydes and KSCN in aqueous solution was investigated. The reactions was catalyzed by a combination of CuI and 1,10-phenanthroline with Cs2CO3 as a base and in neat water at 100 ℃ for 30 min. A variety of benzothiazoles can be synthesized in an excellent yield up to 94%.

Key words: microwave-assisted synthesis, iodoaniline, aldehyde, benzothiazoles
