Abstract

L'invention concerne des procédés d'hydrocyanation de mono-oléfines aliphatiques non-conjuguées ou de mono-oléfines conjuguées avec un groupe ester. On utilise dans ces procédés une composition de précurseur de catalyseur comprenant un ligand asymétrique au phosphite bidenté et du nickel de valence zéro, de préférence en présence d'un acide de Lewis servant de promoteur, pour produire un composé organique portant un groupe nitrile terminal. On décrit également des compositions de précurseurs de catalyseur.
