A succinimide-N-sulfonic acid catalyst for acetylation reactions in absence of a solvent
Shirini, Farhad,Khaligh, Nader Ghaffari
, p. 695 - 703 (2013)
A small amount of succinimide-N-sulfonic acid efficiently catalyzed the acetylation of a variety alcohols, phenols, thiols, amines and aldehydes with acetic anhydride at room temperature under solvent free conditions. This catalyst has the advantages of excellent yields and short reaction times and the reaction can be carried out on a large scale, which makes it potentially useful for industrial applications.
A convenient and efficient protocol for the synthesis of acylals catalyzed by Br?nsted acidic ionic liquids under ultrasonic irradiation
Borikar, Sanjay P.,Daniel, Thomas
experimental part, p. 928 - 931 (2012/03/08)
The synthesis of acylals (1,1-diacetates) via the reactions of aldehydes with acetic anhydride was carried out in 85-97% yields at room temperature under ultrasound irradiation catalyzed by the Br?nsted acidic ionic liquid [bmpy]HSO4. This method provides several advantages, such as solvent-free conditions, operational simplicity, higher yields, and reduced environmental consequences. The ionic liquid was recovered and reused.
A mild and efficient method for the chemoselective synthesis of acylals from aldehydes and their deprotections catalysed by ceric ammonium nitrate
Roy, Subhas Chandra,Banerjee, Biplab

A mild and efficient method has been developed for the chemoselective synthesis of geminal diacetates (acylals) from aldehydes using acetic anhydride in the presence of a catalytic amount of ceric ammonium nitrate in excellent yield. Ketones are found to be unaffected under the reaction conditions. The deprotections of acylals by using water and ceric ammonium nitrate have also been achieved.
