Abstract
New nitrosoarene complexes of Ru(II), Pd(II), Pt(II), and Rh(I) have been synthesized. Their reactions with CO in the solid state and in ethanol suspension suggest formation of a nitrene intermediate. The catalytic redn. of nitrosobenzene has been also studied; azoxybenzene and urethane are the main products in ethanol, whereas azoxybenzene, Ph isocyanate and diphenylurea are obtained in benzene. Increase in the temp. and the CO pressure results in increase of the yields of the carbonylated products.File in questo prodotto:
