Merajoddin Department of Chemistry,Berakly Journal Article 2010 07 18 A highly ecient, simple and rapid method for the chemoselective preparation of acylals from aldehydes and acetic anhydride in the presence of a catalytic amount of poly(ethylene glycol)-bound sulfonic acid (PEG-SO3H) (1.67 mol%) at room temperature is described. Ketones do not react under these reaction conditions. https://scientiairanica.sharif.edu/article_3307_800ebea20ccc514ce561dcb2a8299d85.pdf
