Abstract
The present invention relates to a method of oligomerizing olefins M selectively to oligomers M, 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 Vm, and a micro- or mesoporous solid whose average micropore diameter Φ is greater than or equal to Φdefined as a function of the molecular volume (Vm+nVm), where n is the number of monomeric olefins strung together upon obtaining the metallacycle intermediate and Vmthe molecular volume of the monomeric olefin.
