Abstract

•Benzo[g]chromenes were synthesizedby using nano-Fe3O4/polyethylene glycol (PEG).•A convenient sonochemical method is described for the preparation of chromenes.•Good to excellent yields were achieved within shorter reaction time.•High catalytic activity and reusability of nano catalyst were observed.

In this research, a general synthetic method for the synthesis of benzo[g]chromenes has been developed using Fe3O4/polyethylene glycol (PEG) core/shell nanoparticle under ultrasonic irradiations. Compared to the conventional methods, ultrasound procedure showed several advantages including mild reaction conditions, high yield products, short reaction times, reusability of the catalyst and little catalyst loading.
