ABSTRACT:
A method for the preparation of aromatic hydroxythiols including oxidizing an aromatic aminothiol to form an aminodisulfide compound; forming a bis-diazonium salt of the aminodisulfide compound; and reacting the bis-diazonium salt with water to form an aromatic hydroxyldisulfide compound, which is then reduced to the hydroxythiol. New bis-diazonium aromatic disulfide compounds are also disclosed.
