Patent ID: 8901334

Claim:
A transition metal catalyst comprising monomeric units of the general Formula I: [MNPR 3 ] Formula I where M is a first row transition metal having a +1 oxidation state; R 3 PN − is a monoanioinic phosphoranimide ligand of structure: where: R 1 , R 2 , R 3 can be the same group or different groups; R 1 , R 2 , R 3 =alkyl (C1-18, primary, secondary and tertiary alkyl), cycloalkyl (C3-C8), aryl/heteroaryl, substituted aryl/heteroaryl or an inert functional group containing at least one heteroatom selected from the group consisting of a Group 15 and/or Group 16 element; R 1 , R 2 , R 3 may also be linked to give cyclic systems, using linkages such as aliphatic cyclic systems; wherein the M to R 3 PN − ratio in the catalyst is 1:1.
