Boric acid (BO₃H₃) is an inexpensive, efficient and mild catalyst for the synthesis of 1,1-diacetate (acylal) from the various aromatic and heteroaryl aldehydes with acetic anhydride at room temperature under solvent-free condition.The present method does not involve any hazardous organic solvents or catalysts.This method gives notable advantages such as excellent chemoselectivity,mild reaction condition, short reaction times and excellent yield.
- Aromatic and heteroaryl aldehyde,
- Boric acid,
- 1,1-Diacetate,
- Solvent-free
