The present invention relates to a process for the isomerization of precursor
allyl alcohols of the formula (I) to product allyl alcohols of the formula (II)
##STR1##
where R1 to R5 are hydrogen or a mono- or polyunsaturated
or saturated C1-C12-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),
##STR2##
where
- L1, L2 in each case independently of one another are water 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 p1 a di- or polynuclear
complex is formed, and also to novel oxoperoxotungsten(VI) complexes and to the
use thereof.
