β-ナフトールのロダン化について

抄録

1) Application of potassium thiocyanate and bromine on β-naphthol, in accordance with the formula of Kaufmann or Neu failed to give the expected 1-thiocyano compound, contrary to the original report and in its stead, substances assumed to have been formed secondarily from the expected thiocyano compound, i.e. 1-mercapto-2-naphtholcarboxylate and 2, 2′-dihydroxy-1, 1′-dinaphthyl sulfide, were obtained.
2) Warming of 1-mercapto-2-naphtholcarboxylate with alkali yielded 2, 2′-dihydroxy-1, 1′-dinaphthyl sulfide and disulfide.
3) The structure of the foregoing three compounds were proved by their respective preparation from 2-chloro-2-naphthol.
