Abstract

La présente invention concerne un procédé de préparation d'esters vinyliques d'acides carboxyliques, dans lequel on fait réagir un acide carboxylique avec un composé alcyne en présence d'un catalyseur, choisi parmi des complexes de carbonyle, des halogénures et des oxydes de rhénium, de manganèse, de tungstène, de molybdène, de chrome et de fer et le rhénium métal, à une température inférieure à 300°C. Ce procédé donne les esters vinyliques recherchés avec un rendement élevé.
