  • Hydrosilation process using a (.eta..sup.5 -cyclopentadienyl)tri(.sigma.-aliphatic) platinum complex as the catalyst
    Patent number: 4600484
    Abstract: A process for the addition of compounds containing silicon-bonded hydrogen to compounds containing aliphatic unsaturation. The process is activated by actinic radiation and is conducted in the presence of a platinum complex having one cyclopentadienyl group that is eta-bonded to the platinum atom and three aliphatic groups that are sigma-bonded to the platinum atom.
    Type: Grant
    Filed: October 25, 1984
    Date of Patent: July 15, 1986
    Assignee: Minnesota Mining and Manufacturing Company
    Inventor: Timothy J. Drahnak
  • Radiation activated addition reaction
    Patent number: 4530879
    Abstract: A process for the addition of compounds containing silicon-bonded hydrogen to compounds containing aliphatic unsaturation. The process is activated by actinic radiation and is conducted in the presence of a platinum complex having an ultraviolet displaceable group.
    Type: Grant
    Filed: March 4, 1983
    Date of Patent: July 23, 1985
    Assignee: Minnesota Mining and Manufacturing Company
    Inventor: Timothy J. Drahnak
