Abstract

The catalytic system comprises: PA0 at least one platinum complex of formula LPtX.sub.2 in which L is an organic compound containing at least two phosphorus atoms capable of coordinating platinum and X is a halogen atom, and PA0 at least organic tin compound comprising at least one Sn--O bond and at least one C--O bond. Application to the production of aldehydes by the hydroformlation of an ethylenically unsaturated organic compound, by reacting the said organic compound, at a temperature of between 10.degree. C. and 300.degree. C. and under a pressure of between 1 and 350 bars, with a mixture of carbon monoxide and hydrogen in the presence of an effective amount of the said catalytic system.
