Abstract:
1. A process for the isomerization of precursor allyl alcohols of the formula (I) to product allyl alcohols of the formula (II) where R 1 to R 5 are hydrogen or a mono- or polyunsaturated or saturated C 1 -C 12 -alkyl radical, which may be substituted, in both directions of the equilibrium, wherein the reaction takes place in the presence of an oxoperoxotungsten(VI) complex of the formula (III), where L1, L2 in each case independently of one another are water, hydroxyl, alkoxy or a free coordination site, or are optionally a ligand chosen from the group of aminoalcohols, aminophenols, aminocarboxylic acids or mixtures thereof or mixtures of amines with alcohols, phenols or carboxylic acids, m is the number 1 or 2 n is a number from 1 to 6 p is a number from 1 to 6, where in the case of p>1 a bi- or polynuclear complex is formed.
