A process for the hydroformylation of alpha -substituted, alpha - beta -unsaturated carbonyl compounds in the presence of a catalyst system based on a) a source of rhodium cations and b) a source of ligands of the formula MR1R2R3 wherein M represents a phosphorus, arsenic or antimony atom and R1, R2, and R3 independently represent substituted or non-substituted hydrocarbyl groups, together containing not more than 24 carbon atoms. At least one of R1, R2, and R3 is linked to M via an aliphatic carbon atom. The process is selective for the generation of alpha reaction products.
