Competitive Pseudopericyclic [3,3]- and [3,5]-Sigmatropic Rearrangements of Trichloroacetimidates

The Woodward-Hoffmann rules predict whether concerted pericyclic reactions are allowed or forbidden based on the number of electrons involved and whether the cyclic orbital overlap involves suprafacial or antarafacial orbital overlap. Pseudopericyclic reactions constitute a third class of reactions in which orthogonal orbitals make them orbital symmetry allowed, regardless of the number of electrons involved in the reaction. Based on the recent report of eight-centered ester rearrangements, it is predicted that the isoelectronic eight-centered rearrangements of imidates would also be allowed. We now report that these rearrangements occur, and indeed, an eight-centered rearrangement is slightly favored in at least one case over the well-known six-centered Overman rearrangements, in a trichloroacetimidoylcyclohexadienone, a molecular system where both rearrangements are possible.

Process for dyeing keratinous fibers combining isatin or its derivatives with a tri-, tetra- or pentasubstituted aniline or with a bisphenylalkylenediamine, and dyeing agents

The invention relates to a process for dyeing keratinous fibres, comprising the simultaneous or sequential application of a component (A) containing at least one compound of formula (I): STR1 in which: R1 denotes hydrogen, alkyl, acetyl, benzoyl, phenyl or C1 -C4 carboxyalkyl, R2 and R3 denote hydrogen, alkyl, alkoxy, hydroxyalkyl, amino, halogen, nitro, alkylphenyl, phenyl, alkylamino or hydroxyalkylamino, and a component (B) containing at least (i) a compound of formula (II): STR2 in which: Y denotes OH or NR8 R9, R8 and R9, which are identical or different, denote hydrogen, aminoethyl, hydroxyethyl or C1 -C4 alkyl, R4 to R7 independently of each other denote a hydrogen atom, a C1 -C4 alkyl, a chlorine, a C1 -C4 alkoxy, an acetylamino, an aryloxy, not more than two of the groups R4 to R7 denote a hydrogen atom, excluding 2,5-dimethoxy-1,4-diaminobenzene, and the cosmetically acceptable salts, or (ii) a bisphenylalkylenediamine. It also relates to the dyeing agents for implementing it.
