Efficient and economical access to substituted benzothiazoles: copper-catalyzed coupling of 2-haloanilides with metal sulfides and subsequent condensation.

ABSTRACT

Don't tell azole The first metal-catalyzed direct coupling of metal sulfides with aryl halides and subsequent intramolecular condensation provided substituted benzothiazoles (see scheme). A wide range of functional groups are tolerated under the reaction conditions.
