Abstract: The invention relates to a method for isomerizing educt allyl alcohols of formula (I) into product allyl alcohols of general formula (II) in both directions of the equilibrium, whereby R1 to R5 represent hydrogen or a C1-C12 alkyl radical, which is unsaturated or saturated one or more times and can be optionally substituted. The inventive method is characterized in that the reaction occurs in the presence of a dioxotungsten (VI) complex of general formula (III), whereby: L1 and L2, independent of one another, represent a ligand selected from the group consisting of the amino alcohols, the amino phenols or mixtures thereof, and; m and n represent the number 1 or 2. The invention also relates to novel dioxotungsten (VI) complexes and to their use.
