    Abstract: A phosphazene-supported catalyst in which a support is bonded to a group represented by the general formula (1): wherein n, Zn?, a, b, c, d, R, R1 and D are all defined. The phosphazene-supported catalyst is highly effective to catalyze various organic reactions, and further has no reduction of activity even after recovery and reuse of the catalyst, thus it being economically advantageous. In addition, the polymerization of cyclic monomers, substitution of substituents, carbon-carbon bond forming reactions and the like can be conducted with extremely high efficiency.

  • Patent number: 7994363
    Abstract: A new P-N-P ligand in which each phosphorus atom is bonded to two ortho-fluorine substituted phenyl groups is useful in ethylene oligomerizations. In combination with i) a source of chromium and ii) an activator such as methalumoxane; the ligand of this invention may be used to prepare an oligomer product that contains a mixture of hexenes and octenes. The hexenes and octenes produced with this ligand contain very low levels of internal olefins when produced under preferred reaction conditions.
