Fluorinated alkoxy-imino 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 alcohol-imine pro-ligand of general formula:
• wherein R1 is a substituted phenyl group with H, F, CF3 at positions 2, 3, 4, 5, and 6, or with isopropyl at positions 2 and 6, R2 is hydrogen, C1 to C20 alkyl, C1 to C20 cycloalkyl or C1 to C20 aryl group, optionally substituted with one or more fluorinated alkyl groups, R3 and R4 are each independently selected from perfluorinated alkyl groups, aryl or alkyl group, with the proviso that at least one of R3 and R4 is a perfluorinated alkyl group.
