A chemoselective method for the dithioacetalization of carbonyl compounds using reusable nanosilica-sulfuric acid as a catalyst

A chemoselective and efficient thioacetalization of carbonyl compounds was achieved in exelent yields atroom temperature using 1,2–ethandithiol in the presens of catalytic amount of nano silica –sulfuric acid.
