Abstract
Alkyl carboxylates of the formula: EQU R--CO--O--CH.sub.2 R' are prepared by hydrocarbonylating a compound of the formula: EQU R--CO--O--R' in the simultaneous presence, in the reaction medium, of cobalt, ruthenium, an alkyl iodide and an ionic iodide, the atomic ratio Co/Ru being less than or equal to 1, and the total amount of iodine-containing promoters present in the medium being such that I/Ru is greater than or equal to 5.
