Syntheses of Mercaptobenzoic Acids and Mercaptopyridines Using Elemental Sulfur in the Presence of NaOH-KOH

Mercaptobenzoic acids and mercaptopyridines were synthesized by using mercaptylation of halogeno compounds with elemental sulfur in the presence of molten salts (NaOH-KOH). This procedure was also applied to the preparation of selenoaryl compounds by using elemental selenium. Based on the behavior o...

Zusammenfassung:Mercaptobenzoic acids and mercaptopyridines were synthesized by using mercaptylation of halogeno compounds with elemental sulfur in the presence of molten salts (NaOH-KOH). This procedure was also applied to the preparation of selenoaryl compounds by using elemental selenium. Based on the behavior of the molten salts and sulfur, Na2S and K2S were considered to be the active species for the mercaptylation.
