- Radiochemical addition of alcohols to perfluoro-2-alkenes
-
Radical addition of aliphatic alcohols to internal perfluorinated olefins has been studied. The process occurs non-stereoselectively to give equimolar mixtures of diastereoisomers in all cases.

- ESR SPECTRA OF SPIN-ADDUCTS OF HYDROXYALKYL RADICALS WITH PERFLUORO-4-METHYL-2-PENTENE
-
A study was carried out on the ESR spectra of the spin-adducts of hydroxyalkyl radicals with perfluoro-4-methyl-2-pentene (I) formed upon the photolysis of alcoholic solutions of this perfluoroolefin.The stable conformational positions of the substituents in the spin-adducts depend on the structure of the hydroxyalkyl radicals.The spin-sadducts are annihilated as a consequence of hydrogen atom abstraction as indicated in a preparative experiment.

- HYDROFLUOROETHER COMPOUNDS AND PROCESSES FOR THEIR PREPARATION AND USE
-
A hydrofluoroether compound comprises two terminal fluoroalkyl groups and an intervening substituted or unsubstituted oxymethylene group, each of the fluoroalkyl groups comprising only one hydrogen atom and, optionally, at least one catenated (that is, in-chain) heteroatom; with the proviso that the hydrogen atom is part of a monofluoromethylene moiety.

- MANUFACTURE OF FLUORINATED ALCOHOLS
-
Present invention relates to a process for the manufacture of fluorinated alcohols as well as borates which are employed in the manufacture of the fluorinated alcohols. Fluorinated alcohols of the formulae HOCHRCF(CF3)CHFCF(CF3)2 and HOCHRCF(CF(CF3)2)CHFCF3, HOCHRCF(CF2CF3)CH(CF3)2 and HOCHRC(CF3)2CHFCF2CF3 are made by heating a mixture of a borate of the formula (RCH2O)3B, wherein R═H or a C1 to C7 alkyl group, with perfluoro-4-methyl-2-pentene or perfluoro-2-methyl-2-pentene and a free-radical initiator to form a mixture of borates, optionally separating the mixture of borates from any reactants, solvents, and by-products; hydrolyzing the mixture of borates to form a hydrolysis product mixture; and separating the alcohols from the hydrolysis product mixture.
