Abstract

L'invention concerne un procédé de préparation de thioxanthones éventuellement substituées. Selon le procédé de l'invention, on fait réagir une o,o'-dihalogénobenzophénone avec un sulfure ou un hydrogénosulfure métallique. Les thioxanthones éventuellement substituées ainsi obtenues peuvent être utilisées comme agents initiateurs de photopolymérisation.
