摘要:2-Arylsubstituted Benzimidazoles,Quinoxalines,In 3,5-Position Substituted 2,6-Dimethylpyridines,And 1,4-Bis(Alkylamino)-9,10-Anthracenediones Are Easily Prepared Under Mild Conditions By Means Of Benzofuroxan As Oxidant. Thus,The Preparation Of 2-Arylbenzimidazoles Succeeds In Acetonitrile At 50-Degrees-C In Yields Of 65 To 78 %.

摘要: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.
