The present disclosure provides catalyst compounds represented by Formula (I): where Q is OR13, SR13, NR13R14, PR13R14, or a heterocyclic ring; each R1-14 is independently hydrogen, C1-C40 hydrocarbyl, substituted C1-C40 hydrocarbyl, a heteroatom, or a heteroatom-containing group, or multiple R1-14 are joined together to form a C4-C62 cyclic, heterocyclic, or polycyclic ring structure, or combination(s) thereof; each X1 and X2 is independently C1-C20 hydrocarbyl, substituted C1-C20 hydrocarbyl, a heteroatom, or a heteroatom-containing group, or X1 and X2 join together to form a C4-C62 cyclic, heterocyclic, or polycyclic ring structure; and Y is a hydrocarbyl. The present disclosure also provides catalyst systems including an activator, a support, and a catalyst of the present disclosure. The present disclosure also provides polymerization processes including introducing olefin monomers to a catalyst system. Additionally, the present disclosure provides a polyolefin formed by a catalyst system or method of the present disclosure.
