Abstract
A fluorine-containing vinyl ether compound of the formula: CF(CHCF)(CFCF)(CHCH)OCH═CHis produced by subjecting a fluorine-containing alcohol of the formula: CF(CHCF)(CFCF)(CHCH)OH wherein n is an integer of 1 to 6, a is an integer of 1 to 4, b is an integer of 1 to 3, and c is an integer of 1 to 3, and 2-haloethyl vinyl ether of the formula: XCHCHOCH═CHto XCHCHOH-elimination reaction in the presence of a palladium-based catalyst and an aliphatic amine. The fluorine-containing vinyl ether compound contain a perfluoroalkyl group having 6 or less carbon atoms, which is said to have low bioaccumulation potential.
