Multidentate Lewis Base Catalysts and Methods for use Thereof

A catalyst compound represented by the Formula (I):

• wherein:
• M is a group 3, 4, 5, or 6 transition metal or Lanthanide;
• E is O, S, or NR99, where R99 is hydrogen, C1-C40 hydrocarbyl, C1-C40 substituted hydrocarbyl, monovalent heteroatom, or a monovalent substituted heteroatom group;
• Q is group 14, 15, or 16 atom that forms a bond to metal M;
• A1 and A1′ are independently C, N, or C(R32), where R32 is selected from hydrogen, C1-C20 hydrocarbyl, C1-C20 substituted hydrocarbyl, monovalent heteroatom, or a monovalent substituted heteroatom group;
• A1QA1′ are part of a heterocyclic Lewis base containing 4 to 40 non-hydrogen atoms;
• A2 and A3 are independently a group 14 atom;
• each R5′ and R6′ is independently hydrogen, C1-C40 hydrocarbyl, C1-C40 substituted hydrocarbyl, monovalent heteroatom, or a monovalent substituted heteroatom group;
• R6′-A2=A3-R5′ is a divalent group containing 2 to 40 non-hydrogen atoms, where R5′ and R6′ optionally join to form a hydrocarbyl ring, a substituted hydrocarbyl ring, a heterocyclic ring, or a substituted heterocyclic ring, where the ring has 5, 6, 7, or 8 ring atoms, and where substituents on the ring can join to form one or more additional hydrocarbyl rings, substituted hydrocarbyl rings, heterocyclic rings, or substituted heterocyclic rings, said rings having 5, 6, 7, or 8 ring atoms;
• L′ is a neutral Lewis base joined to the heterocyclic Lewis base containing A1QA1′;
• X′ is an anionic ligand that is optionally joined to L′;
• L is a neutral Lewis base;
• X is an anionic ligand;
• n is 1 or 2;
• m is 0 or 1;
• n+m is 0, 1 or 2;
• each of R1, R2, R3, and R4 is independently hydrogen, C1-C40 hydrocarbyl, C1-C40 substituted hydrocarbyl, monovalent heteroatom, or a monovalent substituted heteroatom group, or optionally one or more of R1 and R2, R2 and R3, R3 and R4, join to form a hydrocarbyl ring, substituted hydrocarbyl ring, heterocyclic ring, or substituted heterocyclic ring, said ring having 5, 6, 7, or 8 ring atoms, and where substituents on the ring can join to form one or more additional hydrocarbyl rings, substituted hydrocarbyl rings, heterocyclic rings, or substituted heterocyclic rings, said rings having 5, 6, 7, or 8 ring atoms;
• and
• an X group may be joined to an L group to form a monoanionic bidentate group, and any two X groups may be joined together to form a dianionic ligand group.
