Process for preparing diesters of malonic acid

Disclosed is an improved process for preparing diesters of malonic acid by subjecting ketene, carbon monoxide and an ester of nitrous acid to a liquid phase reaction in an organic solvent, in which the reaction is carried out in the presence of a catalyst of a platinum group metal complex represented by the formula: wherein, L represents a ligand selected from the group consisting of triorganophosphines, triorganophosphite and triorganoarsines; M represents a platinum group metal; and X represents a halogen or an acetic acid ion.
