【摘要】An environmentally and economically sustainable synthesis of 2-benzoxazyl ketones and 2-benzothiazyl ke- tones through FeC13·6H2O 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.
