  • Patent number: 6576768
    Abstract: Preparation of alkylthio and/or arylthio-substituted diketo-diaryl-pyrrolopyrroles (DPPs) of the formula Ia and dithio-bridged bis-diketo-diaryl-pyrrolopyrroles (bis-DPPs) of the 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 the 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 the formula IIb in which Hal is halogen such as fluorine, chlorine, bromine or iodine, and G6 is G1, and also novel DPPs a

  • Patent number: 6570019
    Abstract: The object of the present invention are diketopyrrolopyrroles of the general formula (I) wherein, independently of one another, Q1 and Q2 represent an optionally substituted, aromatic, isocyclic or heterocyclic group with 5 to 14 atoms in the ring, the heterocyclic group containing at least one oxygen, nitrogen or sulfur atom, and the R1 and R2 groups, independently of one another represent hydrogen or a Y—B+A− group, with the proviso that at least one of the R1 and R2 groups is not hydrogen; B+ is an aromatic, aliphatic, alicyclic, aromatic heterocyclic or non-aromatic heterocyclic, quaternary ammonium group or a quaternary phosphonium group; Y is an optionally substituted linear or branched C1 to C6 alkylene group and A− is an anion; a method for their synthesis as well as agents, containing compounds of formula (I), for dyeing keratin fibers.
