The present invention relates to a catalyst suitable for oligomerization of olefins which is prepared by a process which comprises reacting a catalyst precursor ligand having a formula <IMAGE> wherein R1 and R2 each independently is an alkyl, alkoxy, aryl, or aryloxy group having from about 1 to about 20 carbon atoms, with the proviso that R1 and R2 are not both aryl, or R1 and R2 together form a divalent hydrocarbon moiety, and X is 1,2-arylene, O-CH2, S-CH2, or Se-CH2 with a deprotonation source, a transition metal compound and a catalyst activator. The invention further relates to an oligomerization process utilizing this catalyst.
