A process for hydrocyanation of an aliphatic monoethylenically unsaturated compound, in which the ethylenic double bond is not conjugated to any other unsaturated group in the molecule, or a monoethylenically unsaturated compound in which the ethylenic double bond is conjugated to an ester group, which process uses a catalyst composition comprising a zero-valent nickel and a multidentate phosphite ligand in the presence of a Lewis acid promoter.
Procédé d'hydrocyanuration d'un composé aliphatique monoéthylèniquement insaturé, dans lequel la double liaison éthylénique n'est conjuguée à aucun autre groupe insaturé de la molécule ou d'un composé monoéthylèniquement insaturé, dans lequel la double liaison éthylènique est conjuguée à un groupe ester. Ce procédé utilise une composition de catalyseur comprenant un nickel à valence zéro et un ligand de phosphite polydenté en présence d'un promoteur d'acide de Lewis.
