Abstract
The invention concerns a method for hydrocyanation of ethylenically unsaturated organic compounds comprising at least a nitrile function. The invention provides a method for hydrocyanation of an ethylenically unsaturated hydrocarbon compound by reacting in liquid medium the hydrogen cyanide in the presence of a catalyst comprising a metal element selected among transition metals and an organophosphorous ligand, characterised in that the organophosphorous ligand is a furylphosphine. The invention is in particular useful for synthesizing adiponitrile from butadiene.
