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.
