The acidified kaolin with sulfuric acid (2 % w/w) catalyzed 1,1-diacetates formation from aldehydes in solvent-free conditions. Both aromatic and aliphatic aldehydes gave high yields (85-95 %) of the corresponding 1, 1-diacetates. Advantages of this method are the use of inexpensive and selective catalyst, with high yields in simple operation, and short reaction time under solvent-free conditions.}, number={1}, journal={Iranian Journal of Catalysis}, publisher={OICC Press}, author={Gordi, Zinat and Eshghi, Hossein}, year={2024}, month={Feb.}, keywords={Solvent-free, Aldehydes, 1-Diacetates, Kaolin, Protection} }
