Abstract:
1. Process for the hydrocyanation of organic compounds comprising at least one ethylenic bond by reaction with hydrogen cyanide in the presence of a catalytic system comprising a transition metal compound and an organophosphorus ligand, wherein the ligand is a phosphine corresponding to the following general formula (I): in which: E represents O or S; N represents 0 or 1; R or alternatively R R R it being understood that one and one alone of the R X is selected from the group consisting of a monocyclic or bicyclic, aromatic carbocyclic or heterocyclic radical having from 2 to 20 carbon atoms; a 1-alkenyl radical optionally exhibiting one or more additional unsaturations in the hydrocarbonaceous chain and having from 2 to 12 carbon atoms; a 1-alkynyl radical optionally exhibiting one or more additional unsaturations in the hydrocarbonaceous chain and having from 2 to 12 carbon atoms; or a —CN, [C Y taking any one of the meanings of R R in which, A represents a hydrogen atom; (C —Ar in which each of the phenyl nuclei is optionally substituted by one or more Z groups as defined below; R
