    Type: Grant
    Filed: March 28, 1997
    Date of Patent: April 21, 1998
    Assignee: British Nuclear Fuels plc
    Inventors: Roy D. Bowden, Martin P. Greenhall, John S. Moilliet, Julie Thomson
  • Preparation of fluoroanilines by electrochemical means
    Patent number: 5279714
    Abstract: A process for the preparation of a compound of Formula A: ##STR1## wherein X.sup.1 and X.sup.2 are independently selected from H or any substituent which does not interfere with the electrochemical reductive fluorination; andZ.sup.1 and Z.sup.2 are each independently selected from H or an electron donating group;which comprises electrochemical reductive fluorination of a compound of Formula B: ##STR2## wherein X.sup.1, X.sup.2, Z.sup.1 and Z.sup.2 are as defined above in a mixture of anhydrous hydrogen fluoride and an alkali metal fluoride.The 4-fluoroanilines find use as intermediates in the manufacture of a wide range of agrochemicals, dyestuffs and pharmaceuticals.
    Type: Grant
    Filed: March 18, 1992
    Date of Patent: January 18, 1994
    Assignee: Imperial Chemical Industries PLC
    Inventors: John S. Moilliet, Ian K. Jones
  • Substituted fluorobenzenes
    Patent number: 5212301
    Abstract: Introduction of a fluoro substituent into an aromatic ring adjacent an electron donating group is difficult producing mixed isomers and low yields of desired products.A process for the introduction of a fluoro substituent into a substantially adjacent position to an electron-donating group into an aromatic compound in high yield is disclosed.The fluoroaromatic compounds are useful as synthetic intermediates for example in the manufacture of agrochemicals, pharmaceuticals and dyestuffs.
    Type: Grant
    Filed: May 8, 1992
    Date of Patent: May 18, 1993
    Assignee: Imperial Chemical Industries PLC
    Inventors: John S. Moilliet, Richard D. Chambers, Michael H. Rock
  • Fluorobenzene derivatives
    Patent number: 5162584
    Abstract: The invention relates to a process for the preparation of aminohalobenzenes which are useful as intermediates in the manufacture of agrochemicals, pharmaceuticals, and dyestuffs. The process involves the simultaneous hydrolysis in an acid medium of the two cyano groups in a 1,3-dicyanoaminohalobenzene to yield an aminohalobenzene.
