Abstract: A method of fluorinating an organic compound comprising reacting an organic compound with a fluorinating agent characterized in that a perfluorocarbon compound is present in the reaction medium. The perfluorocarbon compound may replace an amount of a solvent which would otherwise be required for the reaction to proceed efficiently. The perfluorocarbon compound is readily recoverable after reaction and may be re-used in subsequent reactions. Additives to the reaction medium, such as 18-crown-6, may increase the amoun of solvent which may be replaced. The method is beneficial where solvent consumption would otherwise be large, or where solvent recovery would otherwise be difficult.

Abstract: A method for the fluorination of 1,3-diketones and 1,3-ketoesters is disclosed.

Abstract: New phosphazene derivatives, fully substituted by aromatic groups and perfluoropolyethereal chains, are utilized as stabilizers for oils and greases based on perfluoropoyethers. Such derivatives inhibit the degradation process affecting the perfluoropolyethereal chains when these are subjected to high temperatures in an oxidizing atmosphere and in the presence of metals, such as for example aluminium, titanium, vanadium and their alloys, or steels.

Abstract: Iodine terminated liquid telechelic telomers of chlorotrifluoroethylene (CTFE) containing an average of more than 1 CTFE unit per molecule are novel compounds. The telomers can be prepared by a photochemically initiated reaction between liquified CTFE and either elemental iodine or the telogen ICF.sub.2 CFClI at temperatures below about 50.degree. C.

Abstract: A cotelomer of --CH.sub.2 CF.sub.2 -- (VDF) units and CF.sub.2 CF(CF.sub.3)-- (HFP) units characterized in that the HEP units comprise at least 33% of all VDF and HFP units in the cotelomer combined. Also claimed is a process for preparing a cotelomer in the liquid state comprising reacting (A) a bromine geminal telogen having the general formula RC(R')Br.sub.2 wherein R and R' are selected from the group consisting of F and perfluorinated alkyl radicals having 1 to 8 carbon atoms; (B) 1,1-difluoroethene, and (C) hexafluoropropene, the molar ratio of said components (A):(B):(C) being x:1:1 to x:1:5, in which x is 1 to 5.

Abstract: Introduction of a fluoro substituent into an aromatic ring adjacent an electron donating group is difficult producing mixed isomers and low yields of desired products.A process for the introduction of a fluoro substituent into a substantially adjacent position to an electron-donating group into an aromatic compound in high yield is disclosed.The fluoroaromatic compounds are useful as synthetic intermediates for example in the manufacture of agrochemicals, pharmaceuticals and dyestuffs.
