  Nucleophilic aromatic substitution reactions of 2,4‐dinitrohalobenzene with secondary amines were carried out in deep eutectic solvents (DES) to give excellent yields. The reaction workup involved the addition of water for separating the product, which indicates that DES is an entirely benign reaction medium for the SNAr reactions. More importantly, the DES exhibited excellent recyclability.

  2,4-二硝基卤代苯与仲胺的亲核芳族取代反应在深共熔溶剂（DES）中进行，从而获得了优异的收率。反应后处理涉及添加水以分离产物，这表明DES是用于SNAr反应的完全良性的反应介质。更重要的是，DES表现出出色的可回收性。

  The invention relates to oxidation colorants which are particularly suitable for coloring keratin fiber and to a method of coloring such fiber. The colorants contain as the preliminary oxidation dye at least one diamino aniline of the general formula (I), in which R 1 to R 6 independently of each other are hydrogen, a (C 1- C 4 )-alkyl group, a hydroxy-(C 2- C 3 )-alkyl group, a (C 1- C 4 )-alkoxy-(C 2- C 3 )-alkyl group, an amino-(C 2- C 3 )-alkyl group in which the amino group can also have one or two (C 1- C 4 )-alkyl radicals, or a 2,3-dihydroxypropyl group provided that not all substituents R 1 to R 6 are simultaneously hydrogen, and R 1 and R 2 and/or R 3 and R 4 and/or R 5 and R 6 along with the nitrogen atom to which they are attached are also an aziridine ring, an azetidine ring, a pyrrolidine ring, a piperidine ring, an azepane ring, an azocine ring or a morpholino group, thiomorpholino group or piperazino group which has another substituent R 7 on the nitrogen atom which is selected from hydrogen, a (C 1- C 4 )-alkyl group, a hydroxy-(C 2- C 3 )-alkyl group, a (C 1- C 4 )-alkoxy-(C 2- C 3 )-alkyl group, an amino-(C 2- C 3 )-alkyl group, or a 2,3-dihydroxypropyl group, and the three remaining hydrogen atoms on the benzol ring can also be replaced independently of each other by a halogen atom or a (C 1- C 4 )-alkyl group, or the physiologically tolerable salts thereof with inorganic and organic acids. Shades of color are obtained which have a high level of brilliancy and color fastness.
