Abstract

Un objet de la présente invention est la fourniture d’un nouveau procédé, utile à l’échelle industrielle, pour la production d’un dérivé de 1,3-benzodioxole à grand rendement et laissant peu d’impuretés, y compris une nouvelle réaction de chloration d’un cycle benzénique. Dans le nouveau procédé de production d’un dérivé de 1,3-benzodioxole, la détermination a été faite qu’une nouvelle réaction de chloration cycle benzénique utile à l’échelle industrielle est réalisée au moyen de chlorure de sulfuryle et produit un grand rendement et peu d’impuretés. En fonction de cette constatation, l’invention a été réalisée.
