Methods of dyeing keratin fibers with compositions containing pyrazolo-azole couplers

The present invention relates to a composition for dyeing keratinous fibers, especially human hair, which in a medium appropriate for dyeing comprises: as coupler at least one compound of formula: ?in which: R1is especially hydrogen, alkyl, aryl, a heterocycle, a halogen, etc.; R2is especially hydrogen, halogen, aryloxy, alkoxy, acyloxy, arylthio, alkylthio, heteroarylthio, heteroaryloxy, etc.; Za, Zband Zcare independently a nitrogen atom or a carbon which carries a radical R3or R4whose meanings are identical to those of R1; at least one of Za, Zband Zcis a nitrogen atom; and R3and R4may together form an unsubstituted or substituted aromatic ring; and at least one oxidation base.

Synthesis of mono- and disubstituted 1H-imidazo[1,2-b]pyrazoles

The improved synthesis of 1H-imidazo[1,2-b]pyrazole 1 and of mono- and disubstituted derivatives is described and representative experimental procedures are given. Namely, 2-, 3-, 7- and 6-monosubstituted (2-15k), 2,3- and 6,7-disubstituted (16,17) compounds are prepared and characterized.
