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.
