This paper is dedicated to Professor Rudolf Leuckart for his studies on mercaptans.
In this work, at first, triazenes were synthesized from primary aryl amines. Afterwards,
triazenes were converted into the corresponding thiophenols in one-pot using sodium
sulfide in acidic media, by in situ generation of diazonium counterion beside hydrogen
sulfide as anionic sulfur nucleophile at room temperature. The procedure can be a
convenient shortcut for the preparation of thiophenols from primary aryl amines.
Key words
thiophenol - aryl amine - triazene - diazonium salt - one-pot synthesis
