    摘要: There is described a process for the preparation of compounds of formula I
    in which

    R is hydrogen, optionally substituted alkyl, optionally substituted alkenyl optionally substituted cycloalkyl, optionally substituted phenyl or optionally substituted heterocyclyl, and
    R 1 and R 2 are hydrogen, an organic radical or together with the ring to which they are attached, form an optionally substituted ring, which may contain one or more hetero atoms,
    which comprises reacting a compound of formula II
    with a compound of formula III
    in which the ring Q is an optionally substituted heteroaromatic ring, which optionally comprises one or more further hetero atoms and to which is optionally fused an optionally substituted ring.

    摘要: The present invention relates to a process for preparing fluorinated conjugated olefinic products having, among others, the formulae:

    wherein:
    R x and R y       represent, among others, perhaloalkyl radicals containing from 1 to 10 carbon atoms (in the case of R x ) and from 1 to 9 carbon atoms (in the case of R y ), and
    m      ranges from 2 to 10.
    These olefinic products are obtained by reacting telomeric products having, among others, the formulae:
    R x O-(CFCl-CFCl) m -F
    R x O-(CFCl-CFCl) m -OR x
    F-(CFCl-CFCl) m -F and
    R y -(CFCl-CFCl) m -F
    with zinc powder at temperatures of from about 40°C to about 160°C and in a solvent selected from alcohols, dimethylformamide and dimethylsulfoxide.
    Many of the resulting products are new.
