  • Patent number: 4173517
    Abstract: Dicyclopentadienyl iron (ferrocene) is produced directly from iron and cyclopentadiene, or derivatives thereof, by electrolyzing a conductive salt-containing solution of a monomeric cyclopentadiene compound in an inert solvent, between an iron anode and a cathode which is inert to the electrolyte.
    Type: Grant
    Filed: May 1, 1978
    Date of Patent: November 6, 1979
    Assignee: Studiengesellschaft Kohle mbH
    Inventors: Herbert Lehmkuhl, Wilhelm Eisenbach
  • Patent number: 4104140
    Abstract: Process for reacting an H-acidic organic compound, in which the acidic H-atom is bonded to the organic radical by an oxygen or a sulphur atom, e.g. an alcohol, with a metal having a standard potential which is more positive than -1.66 volts and which at most incompletely reacts with the H-acidic compound under current-free conditions, e.g. Ni, Co, Fe, Mn, Sb, Cu, or Au. The H-acidic compound or a solution thereof is a polar solvent is made conducting by addition of a soluble salt of chlorine, bromine or iodine, and is electrolyzed at a temperature of up to 150.degree. C, using said metal as the anode, for production of the alcoholate.
