WebMechanism of Cyclic Acetal Formation When a ketone or aldehyde is made into its cyclic acetal, the most common reagent of choice for achieving this transformation is using … WebThe first step in the mechanism of acetal formation is acid-catalyzed addition of the alco- hol to the carbonyl group to give a hemiacetal—a compound with an LOR ... To go from the acetal back to the aldehyde or ketone, one simply heats the acetal in aqueous acid. As with all equilibrium reactions, Le Chatelier is king: you get out of it what ...
