1. The preparation of the isomeric compound sporol involved a similar dioxolane formation. 2. The co-monomer is typically dioxolane but ethylene oxide can also be used. 3. Dioxolane is formed by reaction of ethylene glycol with aqueous formaldehyde over an acid catalyst.4. TADDOLs consist of a dioxolane ring substituted with two mutually transoid diarylhydroxymethyl ( Ar 2 COH ) groups. 5. Trioxane and Dioxolane are polymerized using an acid catalyst, often boron trifluoride etherate, BF 3 OEt 2. 6. The dioxolane is expanded to the 1, 3-dioxane system found in sporol at a later step in the synthesis. 7. The use of the urea complex, which gave a water-free material, successfully gave the dioxolane as the major product. 8. "' Dioxolane "'is a peroxide . 1, 3-Dioxolane is used as a solvent and as a comonomer in polyacetals. 9. "' Dioxolane "'is a peroxide . 1, 3-Dioxolane is used as a solvent and as a comonomer in polyacetals. 10. By replacing the 1, 3-dioxolane group with an appropriate ring structure, various other types of putians have been synthesized, e . g.
