Abstract

PURPOSE: To obtain the aimed aromatic urethane compound which is a synthetic intermediate for agricultural chemicals, etc. economically, by reacting an aromatic nitro compound with CO and an organic hydroxyl compound in the presence of a specific co-catalyst.
CONSTITUTION: An aromatic nitro compound is reacted with CO and an organic hydroxyl compound in the presence of a catalyst containing a platinum group metal and the following co-catalyst to give the aimed aromatic urethane compound: At least end of a halide of a metal selected from GroupsIb, IIb, Va, Vb, VIa, VIIa and the iron family and a lamellar compound of graphite is used as the co-catalyst. The co-catalyst is a solid, and easily separated and recovered and reusable with little corrosion of apparatuses.
