The reaction of tetrachloro- and tetrabromophthalic anhydrides and -imides with in situ generated aryl and alkyl thiolates gives mono- to tetrathio-substituted derivatives depending on reagent, stoichiometry, and reaction conditions. The halogens non-vicinal to the carbonyl groups react regio- and chemoselectively under appropriate conditions. By this reaction, novel types of photosensitizers useful to photocross-link polymers are prepared.
