Abstract (en)
[origin: WO0246143A1] The invention relates to a method for the carbonylation of n-pentenoic acid or derivatives thereof of formula (I), wherein R<1> represents CN or COOR<2> and R<2> represents hydrogen, alkyl or aryl. According to said method, a compound of formula (I) is reacted with carbon monoxide and a compound (II) containing a hydroxyl group in the presence of a catalyst system. The method is characterised in that the catalyst system is obtained by reacting a) a source of a metallic ion of a metal (III) of the 8<th> subgroup of the periodic table with b) a bidentate phosphine ligand of formula (IV), wherein R<3>, R<4>, R<5>, R<6>, R<7>, R<8>, R<9>, R<10>, R<11>, R<12>, R<13> and R<14> independently of one another represent an inorganic group, which contains a respective carbon atom, by means of which the respective group is linked to the relevant tertiary carbon atom given in formula (IV), L<1>, L<2>represent independently of one another a lower alkylene group and X represents an arylene group.
