    Filed: March 18, 2003
    Publication date: September 23, 2004
    Inventors: Baiyi Zhao, Kevin R. Squire, Smita Kacker, Jo Ann Marie Canich
  • Late transition metal catalysts for olefin oligomerizations
    Publication number: 20040138056
    Abstract: A series of novel late transition metal catalysts for olefin oligomerization have been invented. The catalysts demonstrate high activity and selectivity for linear &agr;-olefins.
    Type: Application
    Filed: October 24, 2003
    Publication date: July 15, 2004
    Inventors: Baiyi Zhao, Smita Kacker, Jo Ann Marie Canich
  • Soluble late transition metal catalysts for olefin oligomerizations III
    Publication number: 20040044150
    Abstract: A series of soluble &agr;-diimine late transition metal catalysts has been invented comprising a substituted or unsubstituted catecholate ligand. The catalysts demonstrate high activity and selectivity for linear &agr;-olefins. As such, these catalysts conveniently oligomerize ethylene. Typical activators as known to those of ordinary skill in the art are used to activate these transition metal catalysts. These catalysts can be used in a supported or unsupported form.
