Abstract

Novel fluorinated unsaturated glycidyl ethers are prepared by reacting 1,1,1-trifluoro-2-trifluoromethyl-3-buten-2-ol or 1,1,1-trifluoro-2-trifluoromethyl-4-propen-2-ol with chloromethyloxirane in the presence of onium salts. The fluorinated unsaturated glycidyl ethers are, in turn, subject to addition reaction with hydrosilanes in the presence of transition metal catalysts, obtaining novel silicon-modified glycidyl ethers or fluorinated organic silicon compounds.
