Abstract
L'invention a trait à la chimie tinctoriale. Elle concerne un procédé de préparation de 4,9-dihydronaphto-Ø2,3-bõ-thiophene-4,9-diones par réaction d'une 1,4-naphtoquinone éventuellement substituée dans le noyau benzénique, avec le dimère du thioacétaldéhyde en présence d'une base, suivie de la cyclisation de la formylméthylthionaphtoquinone intermédiaire en présence d'un acide. Les produits obtenus par le procédé de l'invention sont intéressants à utiliser comme colorants pour des matières textiles synthétiques et/ou comme composés intermédiaires dans la préparation de colorants.
