We report the reaction between 2,3,5,6-tetrachloro/bromo-1,4-benzoquinones (5A/B) with deprotonated alkoholes/phenoles 7a-e to give yellow 2-alkoxy/phenoxy-3,5,6-trichloro/bromo-1,4-benzoquinones 9A/Ba-e. These reaction products are probably photodegraded yielding the corresponding 2-hydroxy-3,5,6-trichloro/bromo-1,4-benzoquinones 15A/B. The quinones 9A/B are not O-conjugated dehydrated, and the quinones 9Ba-e are not C-3-debrominated. These reactions are observed by photodegradation from 2-dialkylamino-3,5,6-trichloro/bromo-1,4-benzoquinones.

Triphendioxazine reactive dyestuffs of the general formula STR1 with the substituent definition given in the description, are outstandingly suitable for dyeing and printing materials containing hydroxyl groups or amide groups. They give red dyeings with high wet- and light-fastnesses.

Triphendioxazine dyestuffs of the formula STR1 having the substituent meanings specified in the descriptive part, are highly suitable for dyeing and printing hydroxyl- or amido-containing materials, in particular fibre materials, and produce wash-fast dyeings and prints.
