摘要
An environmentally and economically sustainable synthesis of 2-benzoxazyl ketones and 2-benzothiazyl ketones through FeCl3 center dot 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.
