  Bidentate ligand of formula II, R 1 R 2 M 1 —R—M 2 R 3 R 4 (II) wherein M 1 and M 2 are independently P, As or Sb; R 1 , R 2 , R 3 and R 4 independently represent tertiary alkyl groups, or R 1 and R 2 together and/or R 3 and R 4 together represent an optionally substituted bivalent cycloaliphatic group whereby the two free valencies are linked to M 1 or M 2 , and R represents a bivalent aliphatic bridging group containing from 2 to 6 atoms in the bridge, which is substituted with two or more substituents. A catalyst system comprising: a) a source of group VIII metal cations; b) a source of such a bidentate ligand; and c) a source of anions, and use of such a catalyst system in a process for the carbonylation of optionally substituted ethylenically or acetylenically unsaturated compounds by reaction with carbon monoxide and a coreactant is provided.
