“…Lately, the organic–inorganic hybrid, metal–organic framework (MOF) materials have gained an enormous research interest because of their unique properties, such as higher surface area, easy functionalization, and tailorable structure. , Here, we report the first MOF-catalyzed CM reaction to produce asymmetric OCs. In this work, we have developed different acid-modified MIL-101(Cr) MOF materials for the CM reaction of bio-alcohols with DMC to produce asymmetric OCs (Scheme ).…”

The different acid-modified MIL-101(Cr) MOF materials have been exploited for the Lewis acid-catalyzed carboxymethylation (CM) of bio-alcohols to asymmetric organic carbonates (OCs), employing dimethyl carbonate (DMC) as a solvent as well as a reactant. The best catalytic activity was achieved over the acetic acid-modified MIL-101(AA) catalyst, demonstrating 95.3% n-butanol conversion and 84% butyl methyl carbonate (BMC) selectivity. The higher and moderate conversions of primary (1°) and secondary (2°) alcohols, with selectivity equivalent to that of their corresponding OCs, were attained over MIL-101(AA). The higher specific surface area that exposes the maximum number of active sites, and a large amount of Lewis acidic sites that are responsible for the exceptional catalytic performance of MIL-101(AA) were investigated by different characterization techniques, including N 2 -sorption, Py-FTIR, and NH 3 -Temperature Programmed Desorption (TPD) analysis. Other physicochemical properties were examined from Powder X-ray Diffraction (PXRD), Thermogravimteric anaysis (TGA), Fourier Transform Infrared Spectroscopy (FTIR), and Field Emission Scanning Electron Microscopy (FE-SEM) analysis. The characterization data showed a good correlation between the catalytic activities of different MIL-101(Cr) MOF materials and their physicochemical properties. The catalyst was stable up to five recycles and resistant to the leaching of active sites under the employed reaction conditions, confirming the heterogeneity of MIL-101(AA). The present work expands the immense applications of CO 2 -derived DMC and bio-alcohols in green chemistry, which have been extended for sustainable production of OCs.
