New nitrosoarene complexes of ruthenium(II), palladium(II), platinum(II) and rhodium(I) have been synthesized.Their reactions with carbon monoxide have been studied in the solid state and in ethanol suspension.The results suggest formation of a nitrene intermediate.The catalytic reduction of nitrosobenzene has been also studied; azoxybenzene and urethane ate the main products in ethanol whereas azoxybenzene, phenyl isocyanate and diphenyl urea are obtained in benzene.Increase in the temperature and the carbon monoxide pressure results in increase of the yields of the carbonylated products.
