This invention relates to a process useful in the hydrocyanation of olefinic compounds to produce nonconjugated acyclic nitriles, to a process of isomerization of nonconjugated acyclic nitriles to, among other things, 3- and/or 4-monoalkene nitriles and to the hydrocyanation of monoalkene nitriles to produce linear alkyl dinitriles. The processes are performed in the presence of zero-valent nickel and a bidentate phosphorus amide ligand, selected from the group consisting of compounds represented by formula (I), wherein Q is selected from formulae (II), (III), (IV) and (V).
L'invention concerne un procédé utile dans la cyanhydratation de composés oléfiniques, servant à produire des nitriles acycliques non conjuguées, un procédé d'isomérisation de ces nitriles, servant à produire, entre autres, des nitriles 3- et/ou 4-monoalcéniques, ainsi que la cyanhydratation de nitriles monoalcéniques servant à produire des dinitriles d'alkyle linéaires. On exécute ces procédés en présence de nickel de valence zéro et d'un ligand bidenté d'amide de phosphore, choisi dans le groupe des composés correspondant à la formule (I), dans laquelle Q est choisi parmi les formules (II), (III), (IV) et (V).
