METHOD FOR PRODUCING 1,4-DIOXANE DERIVATIVE, 1,4-DIOXANE DERIVATIVE, AND COMPOSITION CONTAINING 1,4-DIOXANE DERIVATIVE, METHOD FOR PRODUCING (1,3-DIOXOLANE)-2-CARBOXYLIC ACID DERIVATIVE, (1,3-DIOXOLANE)-2-CARBOXYLIC ACID DERIVATIVE, AND COMPOSITION CONTAINING (1,3-DIOXOLANE)-2-CARBOXYLIC ACID DERIVATIVE

WIPO Patent Application WO/2022/244715

A1

Provided is a method for producing a 1,4-dioxane derivative represented by formula (2) and/or formula (10), including reacting water, an inorganic base, and fluoroalkene oxide represented by formula (1). Provided is a method for producing a (1,3-dioxolane)-2-carboxylic acid derivative, including: producing a 1,4-dioxane derivative represented by formula (2) and/or formula (10) via the above method; and subjecting the 1,4-dioxane derivative represented by formula (2) and/or formula (10) to ring contraction under heating. In formula (1), R represents a fluorine atom or a fluoroalkyl group. In formula (2) and formula (10), R represents a fluorine atom or a fluoroalkyl group, the two Rs are identical to or different from each other, and М'+ represents a counter cation.
