Novel condensation reactions of O-nitrosobis(trifluoromethyl)hydroxylamine and trifluoronitrosomethane with arsine

Abstract

N-Bis(trifluoromethyl)nitroxy-iminoarsine, (CF3)2NONAsH, is formed by a condensation reaction betweenO- nitrosobis(trifluoromethyl)hydroxylamine and arsine. It undergoes reactions with (CF3)2NO to afford (CF3)2NONAsON(CF3)2 and bis(trifluoromethyl)hydroxylamine. Both the iminoarsines (CF3)2NONAsR (RH, (CF3)2NO) undergo addition reactions across the NAs bond with HI to give (CF3)2NONHAsIR. The reaction of trifluoronitrosomethane and arsine follows a similar pathway, affording an unstable iminoarsine, CF3NAsH, which decomposes via a free-radical mechanism even at low temperatures. © 1994.
