Acylal
From Wikipedia, the free encyclopedia
Acylals in organic chemistry are a group of chemical compounds sharing a functional group with the general structure R-C(OOCR)2. Acylals can be obtained by reaction of aldehydes with acetic anhydride and a suitable catalyst for instance with sulfated zirconia at low temperatures when used as protective groups for aldehydes. High temperature exposure converts the acylal back to the aldehyde.
