    Abstract: There are described dyeing compositions for keratin fibres, and in particular for human hair, containing a dyestuff of the formula: (I) in which A denotes an alkylene group, an alkylene group substituted by one or more OH groups, or an alkylene group interrupted by a hetero-atom such as oxygen or by an -NH- group, R1 and R2, which are identical or different, denote hydrogen, alkyl, monohydroxyalkyl or polyhydroxyalkyl, or R1 and R2 can together form a heterocyclic ring chosen from among piperidino or morpholino groups, Y denotes alkoxy or NO2, R denotes hydrogen or lower alkyl, and if Y denotes alkoxy, Z denotes NO2 and is located in the para-position to the amine group, and if Y denotes NO2, (a) Z denotes alkoxy or OH and is located in the para-position to the NO2 group, or alternatively (b) Z denotes OH and is located in the para-position to the amine group, and also their cosmetically acceptable salts. Many of these dyestuff are novel.

    Abstract: Prepn. of indole derivs. of formula (I) in a single step comprises contacting an N-protected indoline (II) with H2 or hydrogen donor in presence of hydrogenation catalyst with stirring in a solvent at pH at most 7 and at a temp. between ambient and reflux. In (II), R1 is 2-10C alkenyl or benzyl (both opt. substd.); R2-R4 are H, halo (such as Br, Cl, F or I), 1-7C alkyl, aryl, OH, 1-7C alkoxy, 3-7C alkenyloxy, aryloxy, acyloxy, CHO, aroyl, CH2OH, arylhydroxymethyl, COOH, 2-8C alkoxycarbonyl, carbamoyl, amino, mono- or di(1-7C alkyl) amino, 2-8C alkoxycarbonylamino, acylamino, N-(1-7C alkyl) acylamino, di(1-7C alkyl) formamidino or di(1-7C alkoxy) methyl.
