Phosphinyl amidine compounds, metal complexes, catalyst systems, and their use to oligomerize or polymerize olefins

An N2-phosphinyl amidine compound characterized by having the formula:

• wherein:
• R1 is a C1 to C15 alkyl group, a C4 to C20 cycloalkyl group, a C4 to C20 substituted cycloalkyl group, a C6 to C20 aryl group, or a C6 to C20 substituted aryl group,
• R2 is a C1 to C30 organyl group consisting essentially of inert functional groups wherein the inert functional groups are selected from the group consisting of halo groups, nitro groups, hydrocarboxy groups, sulfidyl groups, hydrocarbyl groups, or combinations thereof,
• R3 is hydrogen, and
• R4 and R5 are each independently a C1 to C30 organyl group consisting essentially of inert functional groups wherein the inert functional groups are selected from the group consisting of halo groups, nitro groups, hydrocarboxy groups, sulfidyl groups, hydrocarbyl groups, or combinations thereof.
