Process for the isomerization of precursor allyl alcohols to product allyl alcohols in the presence of tungsten oxo(VI) complexes comprising additional nitrogen-containing ligands at temperatures of from 50 to 300.degree. C., wherein, in the catalyst, as well as the nitrogen bases known as additional nitrogen-containing ligands, or instead of these nitrogen bases, aminoalcohols such as triethanolamine, diethanolamine, monoethanolamine, tripropanolamine, dipropanolamine, 3-amino-1-propanol, 1-amino-2-propanol, 2-amino-1-propanol, butyldiethanolamine, methyldiisopropanolamine, N,N'-bis(2-hydroxybenzyl)-1,2-diaminoethane or N-(2-hydroxybenzyl)amine are present as additional nitrogen-containing ligands. The process is particularly suitable for the preparation of tertiary product allyl alcohols, such as linalool, by isomerizing primary or secondary allyl alcohols, such as geraniol and nerol.

Procedimento per l'isomerizzazione degli alcoli allilici del precursore agli alcoli allilici del prodotto in presenza dei complessi del oxo(VI) del tungsteno che contengono i ligands contenenti azoto supplementari alle temperature di 50 a 300.degree. C., in cui, nel catalizzatore, così come le basi dell'azoto conosciute come i ligands contenenti azoto supplementari, o anziché queste basi dell'azoto, amminoalcool quale trietanolammina, la dietanolammina, la monoetanolamina, il tripropanolamine, il dipropanolamine, 3-amino-1-propanol, 1-amino-2-propanol, 2-amino-1-propanol, il butyldiethanolamine, il methyldiisopropanolamine, la N, N'-bis(2-hydroxybenzyl)-1, 2-diaminoethane o N-(2-hydroxybenzyl)amine sia presente come ligands contenenti azoto supplementari. Il processo è particolarmente adatto a preparazione degli alcoli allilici del prodotto terziario, quale linalolo, isomerizzando gli alcoli allilici primari o secondari, quali geraniolo e nerolo.
