oa South African Journal of Chemistry - A highly efficient solvent-free acetalization of aldehydes to 1,1-diacetates catalyzed by SiO-Pr-SOH : research article



1,1-Diacetates are prepared in excellent yields from aldehydes and acetic anhydride under solvent-free conditions at room temperature in short reaction times using catalytic amount of sulfonic acid functionalized silica (SiO-Pr-SOH) which could be easily handled and removed from the mixture of reaction.
