Nickel catalyst for the cyanation of aromatic halides. |
摘要 |
<p>The invention relates to a nickel compound which can be used as a catalyst, said nickel compound having a central nickel atom complexed by a diphosphine ligand. In said diphosphine ligand the P-atoms are interconnected through a metallocene biradical or an aromatic bivalent radical. The invention also relates to the use of said nickel compound and to a method of preparing an aromatic cyanide from an aromatic halide and an alkali metal cyanide in a substantially anhydrous non-dipolar aprotic solvent under the influence of said phosphine-nickel catalyst, in the presence of a reducing agent.</p> |
