Abstract:

Thiocyanation of various aromatic and heteroaromatic compounds has been achieved using ammonium thiocyanate in the presence of 2,3-dichloro-5,6-dicyanobenzoquinone (DDQ) in methanol solution at room temperature and under reflux condition. The rate of reaction is influenced by the electron-donor ability of the aromatic nucleus.Key words: amines, DDQ, indoles, thiocyanation.

On a effectué la thiocyanatation de divers composés aromatiques et hétéroaromatiques en utilisant du thiocyanate d'ammonium en présence de 2,3-dichloro-5,6-dicyanobenzoquinone (DDQ), en solution dans le méthanol, à la température ambiante ainsi que sous des conditions de reflux du méthanol. La vitesse de la réaction est influencée par le caractère électrodonneur des substituants sur le noyau aromatique.Mots-clés : amines, DDQ, indoles, thiocyanatation.[Traduit par la Rédaction]
