Abstract :A variety of aldehydes react with acetic anhydride in the presence of a catalytic amount of H2SO4-silica to afford the corresponding 1,1-diacetates (acylals) in excellent yields. Ketones are not affected under the reaction conditions. The advantages are the simplicity of the acylation procedure, and the relatively non-toxic nature of the catalyst as well as its easy availability and low cost.Keywords : Acylals, aldehydes, catalysis, solvent-free reactions, H2SO4-silica.
