hexafluoroacetone and nitric oxide to give 2 or of hexafluoroacetone to give 8. Fromreaction of 1 with nitrosyl chloride the major products are nitric oxide, 7-chloro-8,8,8-trifluoro-2-methyl-4,4,7-tris(trifluoromethyl)-5,6-diazaocta-1,5-diene (13) and 5,5-dimethyl-3,3-bis(trifluoromethyl)-1-[2,2,2-trifluoro-1-(trifluoromethyl)ethyl]pyrazolidine (14) formed via decomposition of the 1:1 adduct containing C-chloro

Thermal decomposition of the title compound at 140 °C gives mainly nitrogen, hexafluoroacetone and tetrakis-trifluoromethylhydrazine while reaction with tetrafluoroethylene and chlorotrifluoroethylene affords equimolar mixtures of the 1:1 adducts (CF3)2CNCF2CFXON(CF3)2 and (CF3)2CNCF2CFON(CF3)2 (X=F and Cl) in high yield via four-centre addition or a radical-cage process.

The reactions of bis(trifluoromethyl)nitroxyl with the Group 15 hydrides (CF3)nMH3−n (M = P, As; n = 0, 1) in a ratio of 2:1 proceed rapidly via free-radical mechanisms to afford N,N-bis(trifluoromethyl)hydroxylamine and products which can be rationalised in terms of unstable hydride intermediates (CF3)2NOM(CF3)nH2−n. While the reactions with CF3MH2 (M = P, As) yielded mainly CF3M[ON(CF3)2]2 and (CF3)2NOH

Methane resists attack by bistrifluoromethylnitroxide at room temperature, but hydrogen abstraction occurs with ethane [→ EtR, RCH2·CH2R, MeCOR; R =(CF3)2N·O throughout this paper], propane (→ PriR, MeCHR·-CH2R, Me2CO), isobutane (→ ButR, Me2CR·CH2R), isopentane (→ Me2CREt, Me2CR·CHRMe, RCH2·-CRMeEt), and neopentane (→ ButCH2R, ButCOR).

Treatment of the methyl ethers MeOX (X = Me, Ph) with a stoicheiometric amount of bistrifluoromethylnitroxide [(CF3)2NO·= R·] at room temperature converts them efficiently into their bistrifluoromethylamino-oxymethyl counterparts, RCH2OX; the bis-derivative (RCH2)2O is a minor by-product in the case of dimethyl ether (X = Me). Multiple hydrogen-abstraction increases in importance with diethyl ether
