Title (EN) USE OF NITRILES AS POLAR APROTIC SOLVENTS
(FR) UTILISATION DE NITRILES COMME SOLVANTS APROTIQUES POLAIRES
Abstract: front page image
(EN) The invention concerns the use of aliphatic nitriles with relatively high molecular weight, as polar aprotic solvents, in particular in nucleophilic substitution reactions of the aromatic type. Said nitriles have a molecular mass more 79, preferably more than 90. The invention is useful for synthesis of fluorinated aromatic compounds.
(FR) La présente invention vise l'utilisation de nitriles aliphatiques de poids moléculaire relativement élevé, comme solvants aprotiques polaires, notamment dans des réactions de substitution nucléophile de type aromatique. Ces nitriles présentent une masse moléculaire supérieure à 79, de préférence supérieure à 90. Application à la synthèse de composés fluorés aromatiques.
