Abstract
Trianionic ligand precursor compounds, catalyst systems containing the precursor compounds, and uses of the precursor compounds are described. The present invention also provides constrained geometry catalysts, methods to make the constrained geometry catalysts and methods to use the constrained geometry catalysts in various reaction systems, including polymerization, metathesis reactions, and hydroamination reactions.
