An environmentally and economically sustainable synthesis of 2‐benzoxazyl ketones and 2‐benzothiazyl ketones through FeCl 3 ·6H 2 O catalyzed tandem reactions of alkynyl bromides with 2‐amino(thio)phenols in [bmim]BF 4 has been developed. Remarkable advantages of this new synthetic strategy include high efficiency, readily available starting materials, and recyclable catalyst and reaction medium.
