Synthesis of condensed nitrofuroxanes using hydroxylamine

The possibility of preparing condensed nitrofuroxanes using hydroxylamine was examined.

The reactions of 4-nitrobenzofuroxan with amines in DMSO; kinetic and equilibrium studies

Kinetic and equilibrium studies are reported for the reactions of six aliphatic amines with 4-nitrobenzofuroxan, 3, in dimethyl sulfoxide. Rapid reaction at the 5-position to yield σ-adducts is followed by slower formation of the thermodynamically more stable adducts at the 7-position. 1H NMR spectra are reported. The results are compared with those for reaction of the amines with 1,3,5-trinitrobenzene, 2. These reactions involve the initial formation of zwitterionic intermediates which transfer an amino proton to a second molecule of amine. It is found that the proton-transfer step is less likely to be rate determining in the reactions of 3 than of 2; this may be due to the lower steric requirements of 3.

AMBIPHILIC FUROXAN RING. BENZOFUROXAN OXIDATION BY PERACID AND REDUCTION BY COPPER

Monopersulfuric acid, trifluoroperacetic acid and hydrogen peroxide in polyphosphonic acid, or with selenium dioxide in t-butyl alcohol, or in tetramethylene sulfone have each oxidized benzofuroxan into o-dinitrobenzene.Monopersulfuric acid oxidized 4-nitrobenzofuroxan into 1,2,3-trinitrobenzene (80percent) and 4,6-dinitrobenzofuroxan into 1,2,3,5-tetranitrobenzene (99percent); hydrogen peroxide in polyphosphoric acid was moderately efficient for the latter oxidation.Copper in acidified ethanol transformed 4,6-dinitrobenzofuroxan into picramide quantitatively.

Kinetic studies of the reactions of 4-nitrobenzofuroxan with cyanide ion and isopropoxide ion in isopropanol

Kinetic studies of the reactions in isopropanol of 4-nitrobenzofuroxan with cyanide ion and isopropoxide ion have been carried out over the temperature range 15.0 to 35.0 deg C.For both bases, the first species identifiable using stopped-flow reaction techniques is postulated to be a C-7 ?-complex of 4-nitrobenzofuroxan and base.Specific rate constants and activation parameters for the formation of these ?-complexes are compared to corresponding data relating to the formation of cyanide ion and isopropoxide ion - ?-complexes of 1,3,5-trinitrobenzene in isopropanol.
