A process for the preparation of acetals by reacting one or more ethylenically unsaturated compounds with carbon monoxide, hydrogen and a liquid or dissolved organic nucleophilic compound containing at least two vicinal hydroxy groups in the presence of a catalyst system comprising: a) a source of plantinum; b) a source of anions; and c) a bidentate ligand of the formula R1R2M1RM2R3R4(I) wherein M1 and M2 independently represent a phosphorus, arsenic or antimony atom, R represents a bivalent organic bridging group containing from 1 to 4 atoms in the bridge, R1 and R2 together represent a bivalent substituted or non-substituted cyclic group whereby the two free valencies are linked to M1 and R3 and R4 independently represent a substituted or non-substituted hydrocarbyl group, or together represent a bivalent substituted or non-substituted cyclic group whereby the two free valencies are linked to M2.
