Abstract

Procédé de préparation des composés de formule dans laquelle X signifie O ou S, les symboles R signifient un reste aromatique condensé, R1 signifie un radical organique et n' signifie 0,1,2 ou 3, qui consiste à faire réagir un composé de formule II où les deux symboles R3 signifient un groupe alcoxy ou bien l'un des symboles R3 signifie un groupe alcoxy et l'autre un atome d'halogène, avec le soufre en milieu alcalin, un sulfure métallique ou un hydrogénosulfure métallique. Les composés de formule I et II sont utiles comme agents initiateurs de photopolymérisation.
