Abstract:
A fluorine-containing vinyl ether compound of the formula: CnF2n+1(CH2CF2)a(CF2CF2)b(CH2CH2)cOCH═CH2 is produced by subjecting a fluorine-containing alcohol of the formula: CnF2n+1(CH2CF2)a(CF2CF2)b(CH2CH2)cOH 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: XCH2CH2OCH═CH2 to XCH2CH2OH-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.
