Abstract
The present invention relates to a method of oligomerizing olefins M selectively to oligomers Mn, involving a catalytic system comprising at least one organometallic complex with a metal of groups 4 to 10 of the periodic table of molecular volume Vmo, and a micro- or mesoporous solid whose average micropore diameter Φ is greater than or equal to Φmin defined as a function of the molecular volume (Vmo+nVmM), where n is the number of monomeric olefins strung together upon obtaining the metallacycle intermediate and VmM the molecular volume of the monomeric olefin.
