Abstract

Phosphorus pentoxide supported on silica gel (P2O5/SiO2) efficiently acts as a highly active and reusable catalyst for cyclic and non-cyclic S, S-acetalization of a variety of carbonyl compounds under mild, solvent-free and ambient conditions. This method offers significant advantages such as high conversion, clean work-up, short reaction times and simplicity in operation.
