Die Bamberger-Umlagerung zu Amino-phenolen ist oft Ziel der elektrochemischen Reduktion, so z. B. bei der kathodischen Reduktion von 6-Chlor-2-nitro-toluol zu 2-Chlor-4-amino-3-methyl-phenol (an Pt bis 78% d.Th.)2 und von 2-Chlor-l-nitro-benzol zu 3-Chlor-4-amino-phenol (bis 63% d.Th.)3 (die leicht zu 1,4-Benzochinonen oxidiert werden konnen). [Pg.684]

After the electrolytic action. has continued for a suitable period, the contents of the vessel are allowed to cool, following which the unchanged nitro-cymene is separated for re-use, and the l-methyl-2-amino-4-iso-propyl-5-hydroxy benzol is filtered off from the remaining acid solution, whidh latter is strengthened for re-use. The l-methyl-2-amino-4-isopropyl-5-hydroxy benzol is then diazotised, and further reduced in an alkaline solution of stannous chloride, in the usual and well-known manner, with the resulting- production of thymol (l-methyl-4-isopropyl-5-hydroxy benzol). [Pg.256]
