Olefinreaktionen in Gegenwart wolfram- und molybdänhaltiger Katalysatorsysteme vom Ziegler-Natta-Typ

Reactions of Alkenes in the Presence of Tungsten- and Molybdenum-containing Ziegler-Natta-Catalysts In connection with investigations of reactions of alkenes under the conditions of metathesis we studied the reactions of a mixture of 2-pentene/toluene in presence of the catalytic systems WCl₆/EtAlCl₂ and MoCl₅/EtAlCl₂ in homogeneous liquid phase. Alkylation of toluene, metathesis of 2-pentene and also indirect isomerisation of double bonds have been determined in dependence of the molar proportions of 2-pentene/MeCl_x, toluene/2-pentene, and MeCl_x/EtAlCl₂, the addition order (“formation”) of reactants, the “building time” of catalytic system and the reaction time. Compositions of the reaction mixtures have been determined by GLC.
