Mercury nitroxide

Nitroxides, Hydroxylamines, and Nitroso- and Nitro-compounds. The chemistry of the magic radical , bistrifluoromethyl nitroxide, and related compounds particularly (CF3)jN OH and [(CFj),N O],Hg has been dealt with at some length in the review literature full details of the work on reactions between (i) the nitroxide and tetrasulphur tetranitride -> N4S4[O N(CF8)2]4, also obtainable from (CFj),N-0- + N4S4H4 or N3S3CI3 and [(CF3)jN-0]jHg + N3S3CI3, (ii) the mercurial [(CF3)3N-0]3Hg and thiazyl fluoride - ... 

When Blackley and Reinhard first isolated bistrifluoromethyl nitroxide, they found it unreactive towards mercury -a conclusion they have since revised, but perhaps not before Emeleus and Spaziante reported the formation of mercuric bistrifluoromethylnitroxide from the radical and mercury at 20 °C. ...

The hydroxylamine or N-hydroxy compounds can be easily oxidized to nitroxides by a large number of oxidizing agents. The most suitable for this purpose are lead, mercury, or silver oxides. Air, in combination with a catalyst or used alone, may also turn hydroxylamines into nitroxides. For example, the 2,2,5-trimethyl-4-phenyl-3-azahexane-3-oxyl (TIPNO) nitroxide (Table 2, 29) is obtained upon treatment of the corresponding hydroxylamine by a copper(II)-catalyzed oxidation at ambient temperature. When multiple-step synthesis must be carried out prior to oxidation, the hydroxylamine can be protected either by O-acetylation or O-silylation with tert-butylchlorodimethylsilane...
