Abstract

The invention describes a process for the selective dimerization of ethylene to but-1-ene using a catalytic composition comprising at least one organometallic titanium complex, said organometallic complex containing at least one alkoxy type ligand functionalized by a heteroatom selected from nitrogen, oxygen, phosphorus, sulphur, arsenic and antimony or by an aromatic group.
