As part of a program designed to prepare new fluorine-containing monomers, the synthesis of some unsaturated fluoro ethers has been investigated. Earlier work'had shown that free- radioal addition of perhaloalkanes such as bromotrichloromethane, dibromodifluoromethane, and 1, 2-dibromo-2-chloro-1, 1, 2-trifluoroethane to allyl ethers could be accomplished easily to give adducts capable of transformation to both olefinic ...
