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.

Method for making nitrile compounds from ethylenically unsaturated compounds

The invention concerns a method for hydrocyanation of ethylenically unsaturated organic compounds into compounds comprising at least a nitrile function. More particularly, it concerns a method for hydrocyanation of organic compounds comprising at least a ethylenical bond by reacting hydrogen cyanide, in the presence of a catalytic system comprising a transition metal and an organophosphorus ligand. The organophosphorus ligand is a compound with monophosphanorbornadiene structure. The invention concerns in particular hydrocyanation of butadiene into adiponitrile.

Hydrocyanation method for ethylenically unsaturated organic compounds

Catalyst compounds comprising at least one transition metal having an oxidation number of 0 or 1 and at least one sulfonated phosphine are electrochemically synthesized, by electrolyzing an aqueous solution catholyte (contained in the cathode compartment of any suitable electrolytic cell) comprising at least one transition metal compound and at least one sulfonated phosphine.
