Abstract: The reaction of a polyfluorocarbonyl compound such as a polyfluoroketone or polyfluorocarboxylic acid fluoride with fluoride ion and a polyfluoroallyl chloride, bromide or fluorosulfate produces a polyfluoroallyloxy carboxylic acid or ester, e.g., CF.sub.2 .dbd.CFCF.sub.2 OCF.sub.2 CF.sub.2 COOH. The polyfluoroallyloxy compounds copolymerize with ethylenically unsaturated monomers such as tetrafluoroethylene, chlorotrifluoroethylene or vinylidene fluoride to form polymers which are moldable, and in some cases electrically conducting or are water-wettable and dyeable.

Abstract: A fluorovinyl ether having the formulaXRfCF.sub.2 OCF.dbd.CF.sub.2 (I)wherein X represents --H, --Cl, --Br, --F, --CO.sub.2 R, --CONRR', --SO.sub.2 F, ##STR1## or --COF and R represents a C.sub.1 -C.sub.10 alkyl group; R' represents --H or a C.sub.1 -C.sub.10 alkyl group; Rf represents a C.sub.1 -C.sub.20 bifunctional perfluoro-containing group is produced by reacting an iodine-containing ether having the formulaXRfCF.sub.2 OCF.sub.2 CF.sub.2 I (II)in the presence of a catalytic component selected from the group consisting of Mg, Cu, Zn, Zn-Cu, Zn-Cd, Zn-Pd, Zn-Hg, Sn, Sb, organomagnesium compounds and organolithium compounds.

Abstract: Deuterated Isoflurane and anesthetic compositions thereof useful as inhalation anesthetics show reduced levels of inorganic fluoride in urine of anesthetized animals.

Abstract: Deuterated Isoflurane and anesthetic compositions thereof useful as inhalation anesthetics show reduced levels of inorganic fluoride in urine of anesthetized animals.

Abstract: Fluoroorganic compounds are prepared by reacting a haloorganic starting material in which at least one halo atom is replaceable with a fluorine atom by metathetical exchange, with calcium fluoride in the presence of a crown ether and an anhydrous, polar, basic organic solvent which complexes with the calcium ion and contains no --OH groups, at a temperature and for a period of time adequate to effect fluorination.

Abstract: Deuterated halo ethers useful as anesthetics and having lower toxicity than undeuterated analogues further including compositions, and methods of use.

Abstract: Deuterated analogues of methoxyflurane and a method of their use as an anesthetic.

Abstract: A process for the manufacture of the anaesthetic compound CHF.sub.2 --O--CHF--CHF.sub.2 which comprises the reduction of a mono, di- or tri-chlorinated or brominated derivative of the above compound, or the replacement by fluorine of one or more hydrogen, chlorine or bromine atoms in a less-fluorinated derivative of the above compound.
