ABSTRACT:
Strong acids, e.g., aluminosilicates and sulfonic acids are employed as catalysts for the (alkyl or aryl)thiolation of phenols using dialkyl or diaryl disulfides and/or (alkyl- or arylthio)phenols as thiolating agents, and for the isomerization of (alkyl- or arylthio)phenols, to prepare ortho(alkyl- or arylthio)phenols as the predominant products.
