摘要:Advantageous methods for synthesis of fluorinated phthalocyanines are provided. Typical implementation involves a reaction mixture that includes perfluoro compound that is reacted for a reaction period sufficient to yield a fluorinated phthalocyanine of formula F 64 PcM, wherein “Pcâ€? is any phthalocyanine macrocycle and “Mâ€? is hydrogen. Novel fluorinated phthalocyanine molecules/compounds are also provided herein, including specifically compounds that include fluorinated phthalocyanines wherein “Mâ€? is Cu or Vâ•?O. The fluorinated phthalocyanines have wide ranging applications, e.g., corrosion-related applications, coating-related applications, catalysis, and the production of optical and electronic materials.

摘要:A process for the preparation of compounds of the general formula C6Fx(CN)y, wherein x and y are whole integers whose sum equals 6. The process is particularly useful for the synthesis of fluorinated nitriled containing at least two cyano groups (y=2). Among the preferred compounds prepared is tetrafluorophthalonitrile, a key intermediate used as a building block in the pharmaceutical industry. In the process described, tetrafluorophthalonitrile is prepared by the reaction of a chlorinated compound of general formula C6Clx(CN)y wherein x and y are whole integers whose sum equals 6. Specifically, tetrachlorophthalonitrile is reacted with potassium fluoride in an aprotic solvent to prepare tetrafluorophthalonitrile. The fluoronitrile is produced in at least 80 % yield and a minimum purity of 98.5 %. Only one additional recrystallization is required to produce a material of > 99.5 % purity. In another embodiment, the crude tetrafluorophthalonitrile is recrystallized from a hydrocarbon alkane solvent to produce a product of > 99.5 % purity which can be used directly as an intermediate. This process represents an economical means to produce tetrafluorophthalonitrile on an industrial scale.
