Abstract: 
A simple, clean and benign route to the synthesis of 2H-chromen-2-ones derivatives through one-pot condensation of b- ketoesters and substituted phenols in the presence of 1-chloromethyl-4-fluoro-1, 4-diazoniabicyclo [2.2.2] octane bistetrafluoroborateis (SelectfluorTM F-TEDA-BF4) as catalyst under solvent free reaction conditions was experimented. The application of ultrasonic irradiation improved the yields and reduced the reaction times. The use of selectfluor catalyst is feasible because of its stability, commercial value, easy handling, easy recovery and good activity. To extend our research, the ability of selectfluor for the synthesis of 2-aminochromene derivatives was also examined.
