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:Method of preparation of trifluoromethyl copper and trifluoromethyl aromatics
发明人：BURTON DONALD J; WIEMERS DENISE M; EASDON JEROME C
权利人:UNIV IOWA RES FOUND
摘要:The process of direct synthesis of trifluoromethyl copper and trifluoromethyl aromatics, both intermediate reagents useful in direct synthesis of certain perfluoroalkyl compounds. The process involves a direct reaction between on the one hand an aromatic halide and a difluorodihalomethane and on the other hand copper and a difluorodihalomethane.

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.
