First claim

Opening claim text (preview).

What is claimed is: 1. A catalyst compound represented by the formula: wherein the dotted line indicates a dative bond; M is a group 4 metal; each J is, independently, Si or Ge, provided that when z is 2 or more, one JR* 2 group may be CR* 2 ; z is a number from 1 to 12, provided that when z is 2, the two JR* 2 groups may be connected by a heteroatom, X*, to form a group represented by the formula R* 2 J-X*-JR* 2 ; each of R 1 *, R 2 *, R 3 *, R 4 *, and R* is, independently, hydrogen, a substituted C 1 to C 40 hydrocarbyl group, a C 2 to C 40 unsubstituted hydrocarbyl group, or a heteroatom, provided that any adjacent R* groups may form a fused ring or multicenter fused ring system where the rings may be aromatic, partially saturated or saturated; and each X is, independently, a substituted C 1 to C 40 hydrocarbyl group, a C 1 to C 40 unsubstituted hydrocarbyl group, a hydride, an amide, an alkoxide, a sulfide, a phosphide, a halide, an amine, a phosphine, an ether, a combination thereof, or two X's may form a part of a fused ring or a ring system. 2. A compound represented by the formula: wherein the dotted line indicates a dative bond; M is a group 4 metal; each J is, independently, Si or Ge, provided that when z is 2 or more, one JR*s may be CR* 2 ; z is a number from 1 to 12, provided that when z is 2, the two JR* 2 groups may be connected by a heteroatom, X*, to form a group represented by the formula R* 2 J-X*-JR* 2 ; each R* is, independently, hydrogen, a substituted C 1 to C 40 hydrocarbyl group, a C 2 to C 40 unsubstituted hydrocarbyl group, or a heteroatom, provided that any adjacent R* groups may form a fused ring or multicenter fused ring system where the rings may be aromatic, partially saturated or saturated; and each X is, independently, a substituted C 1 to C 40 hydrocarbyl group, a C 1 to C 40 unsubstituted hydrocarbyl group, a hydride, an amide, an alkoxide, a sulfide, a phosphide, a halide, an amine, a phosphine, an ether, a combination thereof, or two X's may form a part of a fused ring or a ring system; each of R 1 , R 2 , R 3 , R 4 , R 5 , R 6 , R 7 , R 8 , R 9 , R 10 , R 11 , R 12 , R 13 , R 14 , R 15 , and R 16 is, independently, hydrogen, a substituted C 1 to C 40 hydrocarbyl group, a C 1 to C 40 unsubstituted hydrocarbyl group, or a heteroatom, provided that any of adjacent R groups may form a fused ring or multicenter fused ring system where the rings may be aromatic, partially saturated or saturated. 3.
