Process for the preparation of an aldehyde through hydroformylation of an unsaturated organic compound in the presence of a catalyst system comprising rhodium or iridium and a multidentate organic phosphite ligand, wherein a monodentate phosphine is present. The process according to the invention can advantageously be carried out for the preparation of methyl-5-formylvalerate, which is an intermediate product in the preparation of .epsilon.-caprolactam or adipic acid, which are in turn raw materials for the preparation of nylon-6 and nylon-6,6, respectively.

Procédé de préparation d'un aldéhyde par hydroformylation d'un composé organique insaturé en présence d'un système de catalyseur comprenant du rhodium ou de l'iridium et un ligand phosphite organique multidenté, dans lequel une phosphine monodentée est présente. Le procédé de l'invention peut être exécuté avantageusement pour la préparation de méthyl-5-formylvalérate, lequel est un produit intermédiaire dans la préparation de .epsilon.-caprolactame ou d'acide adipique, lesquels sont à leur tour les matières premières destinées à la préparation de nylon-6 et de nylon-6,6, respectivement.
