Abstract: The invention relates to a method for producing cyanovaleric acid or esters thereof by reacting 2-, 3- or 4-pentene nitrile or mixtures thereof with carbon monoxide and with a compound containing hydroxyl groups in the presence of a catalyst system. Said catalyst system comprises: (i) a palladium (II) compound, (ii) a bidentate diphosphine ligand and (iii) an anion source. The invention also relates to novel catalyst systems with diphosphine ligands of the bis(phosphinomethyl)amine type.

Abstract: A catalyst system containing subgroup 8 metal(s) or their compounds and a heteropolyacid of molybdenum, tungsten and/or vanadium in a molar excess (based on metal) of at least 2 is used for the oxidative carbonylation of dienes. A process for the oxidative carbonylation of dienes comprises reacting diolefin(s) with a prim., sec. or tert. alcohol, carbon monoxide and oxygen at above 40 deg C in the presence of a catalyst system containing: (a) subgroup 8 metal(s) or their compounds; and (b) a heteropolyacid of formula (I) in a molar excess of at least 2 based on metal. (H)8+a-n(XMo12-a-bWbVaO40)(H2O)y (I) X = phosphorus, silicon, arsenic, germanium, titanium or zirconium; n = 5 if X = P or As, or 4 if X = Si, Ge, Ti or Zr; a = 0-4; b = 0-12; and y = 0-40 An Independent claim is also included for the catalyst system described above.
