an efficient method for the chemoselective synthesis of germinal diacetates from aromatic and heteroaromatic aldehydes using nano silica chloride

in this investigation, nano silica chloride (nano sio2cl) has been found to be efficient, chemoselective and recyclable catalyst for facile and simple synthesis of germinal diacetates from aromatic and heteroaromatic aldehydes in shorter reaction durations. the products were obtained in high to excellent yields. this work consistently has the advantages of excellent yields, short reaction time, mild condition and work-up procedures. this method might be useful in the future for the preparation of similar derivatives.
