Preparation and properties of CF3As[ON(H)CF3]2 and (CF3)2AsON(H)CF3

Trifluoronitrosomethane reacts with trifluoromethylarsine and bis(trifluoromethyl)arsine to afford CF3As[OBN(H)CF3]2 (A) and (CF3)2AsON(H)CF3 (B), respectively. Compound B has been found to decompose at 60 °C to give (CF3)2As(O)H, (CF3)2AsOH and (CF3)2AsF. The reactions of both A and B with anhydrous hydrogen chloride result in the cleavage of the As-O bond to afford quantitative yields of the respective arsenic chloride. Reactions of B with bis(trifluoromethyl)nitroxyl gives (CF3)2AsON(CF3)2, (CF3)2NOH, (CF3)2NH, CF3NO2, CF3NO and a non-volatile white solid.
