AI Technical Summary
Technical Problem
Existing methods for preparing trioxane derivatives suffer from low yield and efficiency, as exemplified by the 40% formaldehyde conversion rate in U.S. Patent Application Publication No. 2017/0233366.
Method used
A method involving the introduction of an ester of formula (I), addition of a compound of formula (II), PtI2, CO, and H2, followed by heating, to convert the ester to a trioxane derivative, with specific conditions such as solvent use and pressure control, allowing for higher yield and selectivity.
Benefits of technology
The method achieves a high yield of 98% with a selectivity of 98.2:1.8, producing a trioxane derivative with high purity and stability.
