A catalyst system for the selective production of isoprenylalkylethers from isoprene is described, characterized by satisfying the following empirical formula PdLxL'y where L is a phosphorated binder in the form of an organic derivative of trivalent phosphorous of type R3P or R2P[CH(R)]zPR2, 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; L' is an easily displaceable binder chosen from dienes, olefins, anhydrides, diketones and nitriles; x is a whole number between 0 and 4 and y is a whole number between 0 and 3, in which system excess phosphorated compounds of R3P or R2P[CH(R)]zPR2 type may or may not be present. |
