    摘要： Preparation of alkylthio and/or arylthio-substituted diketo-diaryl-pyrrolopyrroles (DPPs) of formula (Ia) and dithio-bridged bis-diketo-diaryl-pyrrolopyrroles (bis-DPPs) of formula (Ib), in which in formula (Ia) G is phenyl substituted by at least one arylthio or alkylthio group, and G1 is G or a carbocyclic or heterocyclic radical, by reacting a haloaryl with a thiol or thiolate, and in formula (Ib) G5 is a phenylene, G6 is G1 but not G, and G7 is alkylene, cycloalkylene or phenylene, by reacting two haloaryls with a dithiol or dithiolate, which comprises reacting a thiol or thiolate with a halo-diketo-diaryl-pyrrolopyrrole ('halo-DPP') of formula (IIa) in which G2 is a halogenated phenyl group and G3 is G2 or G1, or reacting a dithiol or dithiolate with two halo-diketo-diaryl-pyrrolopyrroles ('halo-DPPs') of formula (IIb) in which Hal is halogen such as fluorine, chlorine, bromine or iodine, and G6 is G1, and also novel DPPs and also bis-DPPs, compositions comprising DPPs of formula (Ia) prepared in accordance with the invention, and their uses.
