Abstract

3,6-Dichloro-9-phenylxanthylium chlorides of the formula I <IMAGE> in which R1 and R2 denote hydrogen, halogen atoms, alkyl, alkoxy, hydroxyl, carboxylic acid or sulphonic acid groups, are prepared by reaction of a benzotrichloride of the formula II <IMAGE> in which R1 and R2 have the above meanings, with resorcinol in the presence of excess phosphorus oxychloride. The 3,6-dichloro-9-phenylxanthylium chlorides obtained can be used for the preparation of xanthene dyestuffs.
