A catalyst system for the selective production of isoprenyl-alkylethers from isoprene is described, characterised by satisfying the following empirical formula n n n n PdL x L' y n n n nwhere L is a phosphorated binder in the form of an organic derivative of trivalent phosphorus of type R₃P or R₂P[CH(R)] z PR₂, in which the substituents R, which can be identical or different, are either hydrogen atoms or alkyl, cycloalkyl, aryl, alkoxy, aryloxy, arylthio or arylalkyl groups, and in which z is a whole number between 1 and 5; nL' is an easily displaceable binder chosen from dienes, olefins, anhydrides, diketones and nitriles; nx is a whole number between 0 and 4 and y is a whole number between 0 and 3, nin which system excess phosphorated compounds of R₃P or R₂P[CH(R)] z PR₂ type may or may not be present. |
