Abstract
The invention comprises a fluorovinyl ethers having the formula CF3CH2OCF=CXX1 wherein X represents H, F or Cl, and X1 represents H or Cl, and the method of preparing fluorovinyl ethers comprising reacting a polyfluoroethylene having at least one carbon atom to which two fluorine atoms are attached, with an alkali metal alcoholate having the structural formula ROM, where R is a hydrocarbon or hydrocarbon substituted radical such as alkyl, fluoroalkyl or phenyl and M is an alkali metal, under substantially anhydrous conditions, in an inert organic solvent and removing the corresponding fluorovinyl ether product from the reaction mixture. The reaction may be effected between -20 DEG and 150 DEG C. at pressures up to 300 p.s.i. As solvents there may be used benzene, toluene, xylene, dioxan tetrahydrofuran, diisopropyl ether and dibutyl ether. Examples disclose the preparation of ethyl 1-fluoro-2,2-dichlorovinyl ether, ethyl 1,2-difluoro-2-chlorovinyl ether, ethyl 1-fluoro-2-chlorovinyl ether, phenyl 1-fluoro-2,2-dichlorovinyl ether, 2,2,2-trifluoroethyl 11 - fluoro - 21 - chlorovinyl ether, 2,2,2 - trifluoroethyl 11 - fluoro - 21,21 - dichlorovinyl ether, 2,2,2-trifluoroethyl 11,21-difluoro-21-chlorovinyl ether, and 2,2,2-trifluoroethyl 11-fluorovinyl ether.
