4-Dodecylbenzenesulfonic acid (DBSA) has been shown to be an efficient, mild, green, stable and chemoselective
Brønsted acid catalyst for the synthesis of 1, 1-diacetates (acylals) of aldehydes under solvent-free conditions. The
mild condition, eco-friendly, excellent yields, short reaction times and using an easily available, inexpensive and
reusable catalyst are important features of this method.
