AMINO PHOSPHINE

摘要

In one embodiment, this invention provides a ligand described by the formula: (ortho-F-C6H4)2PN(iPr)(ortho-F-C6H4)2 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 produced under preferred reaction conditions.
