METHOD FOR PRODUCING 1,1,2-TRIFLUOROETHYLENE, HEXAFLUORO-1,3-BUTADIENE, OR 1,2-DICHLOROHEXAFLUOROCYCLOBUTANE

Title:

METHOD FOR PRODUCING 1,1,2-TRIFLUOROETHYLENE, HEXAFLUORO-1,3-BUTADIENE, OR 1,2-DICHLOROHEXAFLUOROCYCLOBUTANE

Document Type and Number:

WIPO Patent Application WO/2021/029420

Kind Code:

A1

Abstract:

A method for producing at least one compound selected from the group consisting of 1,1,2-trifluoroethylene, hexafluoro-1,3-butadiene, and 1,2-dichlorohexafluorocyclobutane, the method including a step in which 1,1,2-trifluoro-2-chloroethylene is reacted with an alkali metal having a valence of 0. By this method, at least one compound selected from the group consisting of 1,1,2-trifluoroethylene, hexafluoro-1,3-butadiene, and 1,2-dichlorohexafluorocyclobutane can be obtained under mild conditions with high selectivity.
