标题 :Pyridine derivatives and the N-oxides thereof, and the use thereof as intermediates for the synthesis of plant protecting agents
发明人：FUSS ANDREAS; KOCH VOLKER
权利人:HOECHST AG
摘要:The compounds of the formula I (I) in which A denotes N or N->O, Z denotes O or NH, R denotes H, (halo)alkyl, (halo)alkenyl, (halo)alkynyl or alkoxycarbonyl, R1 denotes hydrogen, halogen, amino, -NHOH, hydroxyl, (substituted) phenylazo or a radical of the formulae Y=C=N-, Y1Y2C=N-, Y3NH- or K denotes 0 or 1, and m and n, independently of one another, denote a number from 1 to 4, with the proviso that, when Z-R denotes OH or NH2, (R1)n denotes at least one radical of the formula or represents two radicals, in the 5 or 6 position of the heterocyclic ring, which, in the 5 position, denote halogen and, in the 6 position, denote a radical of the group comprising halogen, amino, hydroxyl or phenylazo, which may be substituted as specified above, are valuable intermediates in the synthesis of plant protection agents.

标 题 :Synthesis of hydrogen perfluoroalkanes
发明人：DURUAL PIERRE; LANTZ ANDRE
权利人:ATOCHEM ELF SA
摘要:The invention relates to the synthesis of hydrogenperfluoroalkanes R F H, R F denoting a perfluoroalkyl radical containing 2 to 20 carbon atoms, by reaction of the corresponding perfluoroalkyl iodide R F I with an alkali metal hydroxide. n The use of methanol as solvent allows the formation of tars to be avoided, an almost total conversion of R F I and an R F H of excellent purity to be obtained, and the alkali metal iodide by-product to be recovered easily.

标 题 :Manganese catalyzed photopolymerization of fluorinated monomers
发明人：ASANDEI ALEXANDRU D
权利人:UNIV CONNECTICUT
摘要:The disclosure discloses initiating systems for the radical polymerization of alkenes, and especially fluorine substituted alkenes. The polymerization is catalyzed by a metal carbonyl, preferably manganese carbonyl. The polymerization is initiated directly from alkyl halides at room temperature under visible white light. The polymers also allow the synthesis of block copolymers. The process comprises polymerizing at least one alkene monomer in the presence of a halide radical initiator, carbonyl catalyst and a solvent, under reaction conditions and for a time sufficient to polymerize the at least one alkene monomer to form a polymer. The present disclosure provides a method for living polymerization of alkene monomers which provides a high level of macromolecular control over the polymerization process and which leads to uniform and controllable polymeric products. This disclosure also provides a method for activating any halide (Cl, Br, I) chain ends of such polymers for the synthesis of block copolymerizations.

标 题:Synthesis of perfluoroalkyl iodides
发明人：BERTOCCHIO RENE; LACOTE GEORGES; VERGE CHRISTOPHE
权利人:ATOCHEM ELF SA
摘要:The invention relates to a continuous process for the preparation of perfluoroalkyl iodides containing from 4 to 12 carbon atoms by thermal telomerization of tetrafluoroethylene by pentafluoroethyl iodide or heptafluoroisopropyl iodide in a tubular reactor. According to the invention, 30 to 75% of the tetrafluoroethylene is supplied at the head of the reactor; the remainder is introduced at a point in the reactor located between the 2/5 and 3/4 of the length of the tube. The proportion of undesirable heavy telomers is reduced in this way.

摘要:The invention relates to a continuous process for the preparation of perfluoroalkyl iodides by thermal telomerization, in the gas phase, of tetrafluoroethylene with pentafluoroethyl iodide or heptafluoroisopropyl iodide in a tubular reactor. To improve the selectivity for a telomer of the desired extent, the telomers of lesser extent are recycled to at least one point in the reactor, which is situated between one-twentieth and three-quarters the length of the tube.
