Method for catalytic manufacture of aromatic or heteroaromatic nitriles |
摘要 |
<p>Preparation of optionally substituted aromatic or heteroaromatic nitriles (I) by conversion of corresponding halides (or sulfonates) (II) is carried out in presence of (A) copper compounds and (B) monodentate, 5- or 6-membered heteroaromatic amines containing 1-3 nitrogen atoms, using (C) potassium hexacyanoferrate (II) or potassium hexacyanoferrate (III) as cyanide donor. Catalytic preparation of nitriles of formula Ar-CN (I) by conversion of corresponding halides or sulfonates of formula Ar-X (II) is carried out in presence of (A) copper compounds and (B) monodentate, 5- or 6-membered heteroaromatic amines containing 1-3 nitrogen atoms, using (C) potassium hexacyanoferrate (II) or potassium hexacyanoferrate (III) as cyanide donor. X : Cl, Br, I or sulfonate; Ar : optionally substituted aromatic or heteroaromatic residue.</p> |
