| abstract |
The invention relates to a method for the isomerisation of educt allyl alcohols of formula (I) to product allyl alcohols of general formula (II), wherein R<1> to R<5> represent hydrogen or a monounsaturated or polyunsaturated C1-C12 alkyl group, which can optionally be substituted, in both directions of equilibrium. Said method is characterised in that the reaction takes place in the presence of an oxoperoxotungsten (VI) complex of general formula (III), wherein L1 and L2 independently of one another represent water or a free co-ordination site or optionally a ligand, selected from the group containing amino alcohols, amino phenols, amino carboxylic acids or mixtures thereof, or mixtures of amines and alcohols, or amines and phenols or carboxylic acids, m represents the number 1 or 2, n represents a number between 1 and 6, p represents a number between 1 and 6, whereby if p>1, a binuclear or polynuclear complex is formed. The invention also relates to novel oxoperoxotungsten (VI) complexes and to the use thereof. |
