H-Mordenite Zeolite As An Efficient, Rapid and Recyclable Catalyst For Chemoselective Synthesis of 1,1-Diacetates Under Solvent-Free Conditions

In this investigation h-mordenite zeolite has been shown to be an efficient, rapid, green, stable, chemoselective and recyclable catalyst for the synthesis of 1,1-diacetates (acylals) of various aromatic aldehydes under solvent-free conditions at room temperature. the main advantages of this protocol include low catalyst loading, shorter reaction time, excellent yields, eco- friendly, mild-condition, easy work-up procedures and reusable catalyst. this method must be useful in future for the synthesis of similar derivatives. the synthesized zeolite was characterized by various techniques via x-ray diffraction (xrd), scanning electronic microscopy (sem), fourier transform-infrared (ftir spectroscopy) and brunauer–emmett–teller (bet) surface area analysis. the synthesized reaction products were characterized by ftir and 1h nmr technique. further investigation of the application of h-mor zeolite for other reactions is ongoing in our laboratory.
