THE CATALYTIC TRANSFORMATION OF NITROSOBENZENE INTO AZOXY AND AZOBENZENE

Article abstract of DOI:10.1016/S0022-328X(00)89156-1

Nitrosobenzene is converted into azoxybenzene in alcoholic media in the presence of Ru(CO)3(PPh3)2 as catalyst and under an inert atmosphere; Fe(CO)3(PPh3)2 and palladium complexes such as PdL2Cl2 (L = PhNO, p-MeC6H4NH2, PPh3) and Pd3(CO)3(PPh3)4, are less active as catalysts.Under CO pressure and with Ru(CO)3(PPh3)2 as catalyst, nitrosobenzene is converted into azobenzene and aniline, while azoxybenzene gives azobenzene.
