Abstract:The study investigates the catalytic performance of microporous and granular micro–meso–macroporous zeolites (H-ZSM-5 and H-ZSM-5h, respectively) in synthesis of quinolines by the reaction of 2-aminoacetophenone with diketones (2,4-pentanedione or dimedone), known as the Friedländer synthesis. In the presence of H-ZSM-5h, 1-(2,4-dimethylquinolin-3-yl)ethanone (1a) and 3,4-dihydro-3,3,9-trimethyl-1(2H)-acridinone (1b) were produced in 82 and 93% yields, respectively.
