Radical Additions of Heptafluoropropyl Trifluorovinyl Ether

Abstract

The radical addition reactions of heptafluoropropyl trifluorovinyl ether (CF2=CF-O-C3F7) with cyclic ethers such as tetrahydrofuran, tetrahydropyran, 1,4-dioxane and 1,3-dioxolane were investigated to afford the corresponding one to one addition products in fairly high yields in the presence of dibenzoyl peroxide at 60 °C. The method provides a facile way to prepare cyclic ethers possessing fluoroalkyl substituents.
