The invention relates to a composition comprising: i) at least one imidazole coupler of formula (I) with R1, R2 and R3 as defined in the description; ii) at least one oxidation base, preferably of heterocyclic and/or para-phenylenediamine type. The invention also relates to a process for dyeing keratin fibres using ingredients i) and ii); to a kit comprising ingredients i) and ii) and to the use of ingredient i) combined with ii) for dyeing keratin fibres, and to novel couplers. The composition of the invention leads to particularly powerful, chromatic and sparingly selective colourings. Furthermore, the colour build-up on keratin fibres treated with the composition of the invention is very satisfactory.

Direct and efficient catalytic reactions with excellent regioselectivity for the preparation of a series of substituted isoindoles, isoquinolines, and imidazoles are reported. Reaction of C(6)H(4)(2-CN)C[triple bond]C-R with an array of amines, catalyzed by 10 mol % of [sigma:eta(1):eta(5)-(OCH(2))(Me(2)NCH(2))C(2)B(9)H(9)]Ti(NMe(2)) (1), gives a series of substituted isoindoles in very high yields
