A process for producing a urethane compound which comprises reacting at least one compound selected from the group consisting of a primary amine, a secondary amine and a urea compound with carbon monoxide and an organic hydroxyl compound in the presence of a catalyst system comprising:
(a) at least one member selected from the group consisting of platinum group metals and compounds containing at least one platinum group element; and
(b) at least one halogen-containing compound selected from the group consisting of alkali or alkaline earth metal halides, onium halides, compounds capable of forming onium halides in the reaction, oxo acids of halogen atoms and their salts, complex compounds containing halogen ions, organic halides and halogen molecules,
in the presence of molecular oxygen and/or an organic nitro compound as an oxidizing agent at a temperature of from about 80°C to about 300°C under a pressure of from about 1 Kg/cm2 to about 500 Kg/cm2.
