Efficient and Economical Access to Substituted Benzothiazoles: Copper-Catalyzed Coupling of 2-Haloanilides with Metal Sulfides and Subsequent Condensation
Don′t tell azole: The first metal‐catalyzed direct coupling of metalsulfides with aryl halides and subsequent intramolecular condensation provided substitutedbenzothiazoles (see scheme). A wide range of functional groups are tolerated under the reaction conditions.
