University of Tehran Journal of Sciences, Islamic Republic of Iran 1016-1104 16 1 2005 03 01 -Solid Lithium Perchlorate, a Highly Efficient and Chemoselective Catalyst for the Acetalyzation of Aldehydes - 31625 EN Journal Article -A simple, efficient, and general method has been developed for the chemoselective acetalization of aldehydes with 1,3-propanediol, 1,2-ethanediol and trimethyl orthoformate in the presence of solid lithium perchlorate under solvent-free conditions. Both cyclic and acyclic acetals of aldehydes were obtained under environmentally benign conditions in good to excellent yields. https://jsciences.ut.ac.ir/article_31625_8ad2f16f1cfd0d6443a089c0624042b4.pdf
