Phosphinyl Formamidine Compounds, Metal Complexes, Catalyst Systems, and Their Use to Oligomerize or Polymerize Olefins

摘要

N2-phosphinyl formamidine compounds and N2-phosphinyl formamidine metal salt complexes are described. Methods for making N2-phosphinyl formamidine compounds and N2-phosphinyl formamidine metal salt complexes are also disclosed. Catalyst systems utilizing the N2-phosphinyl formamidine metal salt complexes are also disclosed along with the use of the N2-phosphinyl amidine compounds and N2-phosphinyl amidinate metal salt complexes for the oligomerization and/or polymerization of olefins.
