Radical additions to fluoro-olefins. Photochemical mono-fluoroalkylation and sequential bis-fluoroalkylation of oxolane

Oxolane was fluoroalkylated by its photoadditions under atmospheric pressure. Monofluoro-alkylations were carried out with hexafluoropropene (1) and perfluorovinyl ethers C3F7O-[CF(CF3)CF2O]n-CF=CF2 (2-4, n=0-2) by direct photoexcitation of the oleflns to give high yields of addition products 9-12 (81-94%). The reactions were completely regioselective at the oxolane molecule and almost completely regioselective (93-99%) at the double bond of fluoro-olefins; no bis-fluoroalkylated oxolanes were detected. The completely selective introduction of a second fluoroalkyl into position 5 of the oxolane molecule was accomplished by acetone-sensitised photoaddition of 2-fluoroalkylated oxolanes 9, 10 to fluoro-olefins 1 and 2. Byproducts from reactions of the dimethylketyl radical which is formed in the initiation step were isolated and have given some evidence about the reaction mechanism that is discussed.

SURFACE ACTIVE SUBSTANCES CONTAINING AN OLIGO(HEXAFLUOROPROPENE OXIDE) CHAIN AS A HYDROPHOBIC AND OLEOPHOBIC MOIETY

Oil soluble surface active substances, (HFPO)n-Ar, where Ar is an aryl group and (HFPO)n is an oligo(hexafluoropropene oxide) group, n = 2 - 5, were prepared and tested for their surface activities in toluene or m-xylene.Addition of a small amount of (HFPO)4-6-Ar (0.2 - 0.5 wtpercent) was found to decrease remarkably the surface tension of these solvents (down to 12 - 14 dyncm-1 at 20 deg C).Water soluble surfactans (HFPO)n-Ar'SO3Na, where Ar' is an arylene group, were also prepared by sulfonation of (HFPO)n-Ar.Some of these subtances (n = 4 - 6) decreased the surface tension of water down to 16 dyncm-1 at 20 deg C in the concentration of 10-4 - 10-5 molel-1.
