Patentanspruch:Claim: Verfahren zur Herstellung von 2,5-Dichlor-4-alkylmercaptopbenolen der allgemeinen FormelProcess for the preparation of 2,5-dichloro-4-alkyl mercaptopbenols the general formula ClCl Es war nun überraschend, daß bei der Umsetzung von 2,4,5-Trichlorthioanisol nicht analog der Anisolumsetzung das Trichlorphenol bzw. Trichlorthiophenol entstand, sondern unter Austausch eines Chlors in guten Ausbeuten 2,5-Dich!or-4-methylmercaptophenol erhalten wurde.It was now surprising that the conversion of 2,4,5-trichlorothioanisole was not analogous to the conversion of anisole the trichlorophenol or trichlorothiophenol was created, but with the exchange of a chlorine 2,5-dichloro-4-methylmercaptophenol in good yields was obtained.
