Claim Text:
1. A process for oligomerization of olefins into compounds or into a mixture of compounds of the formula C p H 2p with 4≦p≦80, said process comprising: oligomerizing an olefin feedstock in the presence of a catalytic composition comprising at least one organometallic complex of an element of group IV selected from titanium, zirconium, and hafnium, wherein said organometallic complex contains at least one alkoxy ligand functionalized by a heteroatom that is selected from nitrogen, oxygen, phosphorus, and sulfur or by an aromatic group, and said organometallic complex is of the following formula: in which: M is an element from group IV selected from titanium, zirconium, and hafnium, Y is an atom of chlorine or bromine, a hydrocarbyl radical having 1 to 30 carbon atoms, or a radical selected from alkoxy R′O—, amido R′ m is an integer of 1 to 4, and the ligand —OR is an organic compound selected from alkoxy ligands of the formula: in which: (CR R L is —PR X is a hydrocarbon group CR R R n is an integer in the range of 1 to 5.
