Facile Incorporation of Pd(PPh3)2Hal Substituents into Polymethines, Merocyanines, and Perylene Diimides as a Means of Suppressing Intermolecular Interactions

Compounds with polarizable π systems that are susceptible to attack with nucleophiles at C-Hal (Hal = Cl, Br) bonds react with Pd(PPh3)4 to yield net oxidative addition. X-ray structures show that the resulting Pd(PPh3)2Hal groups greatly reduce intermolecular π-π interactions. The Pd-functionalized dyes generally exhibit solution-like absorption spectra in films, whereas their Hal analogues exhibit features attributable to aggregation.

Dyeing method using a specific cationic derivative and a compound selected among a specific aldehyde, a specific ketone, a quinone and a di-imino-isoindoline or 3-amino-isoindolone derivative

Compositions, methods, and kits for dyeing at least one keratin fiber, comprising at least one specific cationic compound and at least one compound chosen from specific aldehydes, specific ketones, quinones, diiminoisoindoline derivatives, and 3-aminoisoindolone derivatives, with the proviso that the inventive compositions do not comprise an oxidizing agent.
