Process for the catalytic production of aromatic or heteroaromatic nitriles |
| abstract |
A process for the preparation of optionally substituted aromatic or heteroaromatic nitriles of the general formula (I) is described DOLLAR A Ar - CN DOLLAR A by reaction of the corresponding aryl halides of the general formula (II) DOLLAR A Ar - X, DOLLAR A wherein X for Chlorine or bromine and Ar represents an optionally substituted aromatic or heteroaromatic radical having 5 to 14 carbon atoms or heteroatoms, with a cyanide of the general formula (III) DOLLAR A M '(CN) ¶n¶, DOLLAR A where M '= Hydrogen, an alkali or alkaline earth metal cation or a quaternary ammonium or phosphonium cation and n = 1 to 4, the reaction in the presence of catalytic amounts of a) a palladium compound, b) a chelating diphosphane or aminophosphine ligand and c) a chelating one Diamins performs. In this way, the desired nitriles can be produced in good yields and selectivities without the use of excessively stoichiometric amounts of salt and without additional reducing heavy metal. |
