Experimental and computational studies have been performed in order to investigate an unusual carbon-carbon bond cleavage that occurs in the preparation of certain benzimidazole N-oxides from anilines. The key factor determining the outcome of the reactio

A continuous flow process for the synthesis of nitrobenzimidazole N-oxides from 2,6-dinitrochlorobenzene and amines or amino acids is reported. The process, performed in a two-step sequence, is faster than previously reported batch processes and avoids so

The invention provides dyeing compositions for keratin fibres, which contain at least one dyestuff corresponding to the formula: STR1 in which R1 and R2 independently of one another denote a hydrogen atom, an alkyl group, a monohydroxyalkyl or polyhydroxyalkyl group, an alkyl group substituted by an alkoxy group, or an aminoalkyl group of which the amino group can optionally be monosubstituted or disubstituted by an alkyl group, and the radical R2 can also denote a phenyl group or a phenyl group substituted by an alkyl, hydroxyl or amino group, and Z denotes a hydrogen atom or an alkyl group, or their cosmetically acceptable salts. Many of the dyestuffs are novel.
