Popis: Silica immobilized sulfuric acid ([3-(propyl)sulfanyl]propyl]ester and N-propylsulfamic acid are employed as recyclable catalysts for the synthesis of 1,1-diacetates from the reaction between an aromatic aldehyde and acetic anhydride under mild- and solvent-free conditions at room temperature. These solid acids could be recycled several times without losing any catalytic activity.
