Patent ID: 7105696

Claim:
A process of hydrocyanation of a hydrocarbon-containing ethylenically unsaturated compound that comprises reaction of said compound in a liquid medium with hydrogen cyanide in the presence of a catalyst that comprises a compound comprising at least one transition metal and at least one organophosphorus ligand, wherein the organophosphorus ligand is a furylphosphine that corresponds to general formula (I) or (II): in which: n represents an integer from 1 to 3, q represents an integer equal to 1 or 2, radicals R 1 , R 2 , R 4 , and R 5 , identical or different, represent a hydrogen atom, a linear or branched alkyl radical that has 1 to 12 carbon atoms that optionally includes heteroatoms, an optionally substituted aromatic or cycloaliphatic radical that optionally includes heteroatoms, a carbonyl, alkoxycarbonyl or alkoxy radical, a halogen atom, a nitrile group or a haloalkyl group that has 1 to 12 carbon atoms, R 3 represents a covalent bond, a linear or branched aliphatic radical that optionally includes heteroatoms, a radical that comprises an optionally substituted aromatic cycle or cycloaliphatic cycle, or several aromatic cycles that are condensed or connected to one another by a covalent bond or by a radical that is formed by an oxygen atom, a sulfur atom or an alkyl radical, and m, p represent an integer from 0 to 3.
