Acetalization was mostly carried out under solvent-free conditions with trialkyl orthoformates, but weakly electrophilic carbonyl compounds and substrates that can coordinate with the catalyst, required the corresponding alcohol as solvent.

Up to now, various mild methods for acetalization and deacetalization have been developed to spare other acid-sensitive functionality, such as the use of catalysts such as ammonium nitrate, Amberlyst or silica gel, and dehydrating agents such as P2O5. Panico,, Russell C. Carcia andJ. Subba R.
