NOVEL CONDENSATION-REACTIONS OF O-NITROSOBIS(TRIFLUOROMETHYL)HYDROXYLAMINE AND TRIFLUORONITROSOMETHANE WITH ARSINE

N-Bis(trifluoromethyl)nitroxy-iminoarsine, (CF3)2NON=AsH, is formed by a condensation reaction between O-nitrosobis(trifluoromethyl)hydroxyl amine and arsine. It undergoes reactions with (CF3)2NO to afford (CF3) 2NON = AsON(CF3)2 and bis(trifluoromethyl)hydroxylamine. Both the imin oarsines (CF3)2NON = ASR (R = H, (CF3)2NO) undergo addition reactions across the N=As bond with HI to give (CF3)2NONHAsIR. The reaction of t rifluoronitrosomethane and arsine follows a similar pathway, affording an unstable iminoarsine, CF3N=AsH, which decomposes via a free-radica l mechanism even at low temperatures.
