An environmentally and economically sustainable synthesis of 2-benzoxazyl ketones and 2-benzothiazyl ketones through FeCl3·6H 2O 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.

experimental part, p. 1568 - 1573 (2012/01/14)
RuCl33H2O catalyzed tandem reaction of alkynyl bromides with 2-aminothiophenols mediated by water is shown to represent a convenient synthesis of 2-benzoylbenzothiazoles. In addition, the Ru(iii) catalyst could be readily recovered and efficiently reused together with water up to three times. CSIRO 2011.
Synthesis of heteroaryl ketones via tandem reaction of 1,1-dibromoethenes
Fan, Xuesen,He, Yan,Zhang, Xinying,Guo, Shenghai,Wang, Yangyang
experimental part, p. 6369 - 6374 (2011/09/12)
A novel method for the synthesis of heteroaryl ketones through one-pot tandem reaction of 1,1-dibromoethenes with 2-amino(thio)phenols promoted by TBAF·3H2O and RuCl3(5%)/air was developed. This novel method includes several reactions in one-pot and utilizes economical yet efficient reagents to generate synthetically and biologically interesting heteroaryl ketones under mild conditions with good efficiency.
