solid. With tris(trifluoromethyl)stibine, no oxidation nor addition reactions occurred. Instead, [(CF3)2NO]3Sb and [(CF3)NO]2SbCF3 were obtained in high yields. The stoichiometry of the reactions suggests that the additional amounts of bis(trifluoromethyl)nitroxyl groups bonded to antimony are derived from the trifluoromethyl groups bonded to antimony. Mechanisms to rationalise these reactions are proposed
