Fluorinated dialkoxy-diimino catalyst components

A metallic complex formed by a process comprising:

• reacting via a metallation reaction, a metal salt or precursor of formula MX4, wherein M is a metal group 4 of the Periodic Table, and wherein each X is the same or different and is a halogen, an alkyl or a benzyl group with a fluorinated dialcohol-diimine pro-ligand of general formula
• wherein R′ is a bridge having from 1 to 6 carbon atoms, which is optionally substituted so that the substituents form a ring either with each other or with R2;
• each R2 is independently selected from hydrogen, C1 to C20 aryl groups or C1 to C20 alkyl groups optionally substituted with one or more fluorinated groups;
• R3 and R4 are each independently selected from CF3, CnF2n+1, wherein n is an integer between 1 and 10, C1 to C20 aryl groups or C1 to C20 alkyl groups;
• and
• R5 and R6 are each independently selected from hydrogen, C1 to C20 aryl groups or C1 to C20 alkyl groups.
