Description
| - The catalytic behavior of metal–organic frameworks Cu-benzene- 1,3,5-tricarboxylate (CuBTC) and Fe-benzene-1,3,5-tricarboxylate (FeBTC) was investigated in the Pechmann condensation of different phenols (resorcinol, pyrogallol, and naphthol) with ethyl acetoacetate and compared with large-pore zeolites beta (BEA) and ultrastable Y (USY). Zeolites BEA and USY exhibited high activity in transformations of the most active substrates (resorcinol and pyrogallol) but a low conversion of naphthol was observed. Almost total transformation of naphthol (94–98% conversion) to the target product was achieved within 24 h of the reaction time over CuBTC and FeBTC. We assume that the regularity in the arrangement of active sites within the framework of CuBTC, which results in the existence of 2 active centers in close proximity, is of critical importance to the transformation of naphthol in the Pechmann reaction that leads to coumarin.
