'''Acylals''' in [[organic chemistry]] are a group of [[chemical compound]]s sharing a [[functional group]] with the general structure R-C(OOCR)<sub>2</sub>. Acylals can be obtained by reaction of [[aldehyde]]s with [[acetic anhydride]] and a suitable [[catalyst]] for instance with sulfated [[zirconia]] {{Ref|Negrón}} at low temperatures when used as [[protective group]]s for aldehydes. High temperature exposure converts the acylal back to the aldehyde.
