Abstract

L'invention concerne un procédé de fabrication du thiényl-2 acétate de méthyle. Ce procédé est caractérisé par le fait que l'on fait réagir à température ambiante du nitrate de thallium III sur une quantité équimoléculaire d'acétylthiophène en milieu méthanolique en presence d'acide perchlorique, qu'après séparation du nitrate de thallium I formé, on dilue avec de l'eau et que l'on extrait le thiényl-2 acétate de méthyle par un solvant. Application à la fabrication du thiényl-2 acétate de méthyle.
