摘要： The manufacturing method of the 1,4-dioxane derivative represented by Formula (2) and/or Formula (10) includes reacting water, an inorganic base, and a fluoroalkene oxide represented by Formula (1). The manufacturing method of the (1,3-dioxolane)-2-carboxylic acid derivative includes manufacturing the 1,4-dioxane derivative represented by Formula (2) and/or Formula (10) by the above manufacturing method and a manufacturing method of the (1,3-dioxolane)-2-carboxylic acid derivative includes manufacturing the 1,4-dioxane derivative represented by Formula (2) and/or Formula (10) comprising ring reduction under heating. In Formula (1), R represents a fluorine atom or a fluoroalkyl group. In Formula (2) and in Formula (10), R represents a fluorine atom or a fluoroalkyl group, two R's present are the same as or different from each other, and M '+ represents a counter cation.
