Abstract

L'invention décrit un nouveau procédé pour préparer cet acide insaturé. On oxyde le 3,3-diméthyl-pent-4-en-1-al avec une suspension aqueuse d'un oxyde de metal de transition (de preférence l'oxyde d'argent humide). L'acide obtenu est un intermédiaire utile pour la préparation d'esters insecticides.
