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.
