| Abstract: | An environmentally and economically sustainable synthesis of 2‐benzoxazyl ketones and 2‐benzothiazyl ketones through FeCl3·6H2O catalyzed tandem reactions of alkynyl bromides with 2‐amino(thio)phenols in bmim]BF4 has been developed. Remarkable advantages of this new synthetic strategy include high efficiency, readily available starting materials, and recyclable catalyst and reaction medium. |
