The bis-hydroxylamine adduct [Fe (tpp)(NH20H)2] is stable at low temperatures, but decomposes to [Fe(tpp)(NO)] at room temperature. [Fe(porphyrin)(NO)] complexes can undergo one-and two-electron reduction the nature of the one-electron reduction product has been established by visible and resonance Raman spectroscopy. Reduction of [Fe(porphyrin)(NO)] complexes in the presence of phenols provides model systems for nitrite reductase conversion of coordinated nitrosyl to ammonia (assimilatory nitrite reduction), while further relevant information is available from the chemistry of [Fe (porphyrin)(N03)]. Iron porphyrin complexes with up to eight nitro substituents have been prepared and shown to catalyze oxidation of hydrocarbons by hydrogen peroxide and the hydroxylation of alkoxybenzenes. ...

Oxidation of 2,3-dimethylbutane-2,3-bis-hydroxylamines with bromine or sodium periodate in aqueous solution at room temperature yielded 3,3,4,4-tetramethyl-A1-l,2-diazetine-l,2-dioxide <1972JA5077, 1975JOC1409> which can be reduced to diazetidine. 

This compound is reduced in two steps to a bis-hydroxylamine which upon treatment with base gives cinnoline. 

Oxidative closure of l,2-bis(hydroxylamines) 20 leads to diazetine dioxides 21 which can be reduced in two steps to 1,2-diazetines 22 (Scheme 14) <1975JOC1409>.

BIS(HYDROXYLAMINE)SULFATE (10039-54-0) A strong oxidizer. Heat or friction may cause explosive decomposition. Violent, possibly explosive, reaction occurs with caustics, reducing agents, or combustible materials. Reacts with alkaline materials, forming unstable hydroxylamine may cause explosive decomposition. Incompatible with sulfuric acid, caustics, aluminum, ammonia, alkylene oxides, aliphatic amines, alkanolamines, amides, isocyanates, magnesium, organic anhydrides, vinyl acetate, epichlorohydrin. 

A pair of Ullman s nitronyl nitroxide radicals carrying m- and p-ethynylphenyl groups at position 2 of the imidazoline ring (7 and 8) are quite stable at room temperature under air and the unpaired electrons withstand the catalyzed polymerization conditions (see Section 11.4.3) [6]. The terminal ethynyl groups are not susceptible to Pb02 in benzene/metha-nol at room temperature, which is used for the oxidation of the bis(hydroxylamine)s to the nitronyl nitroxides [6, 7]. Fremy s salt gives the best result for the oxidation of the hydroxyl-amine 14 carrying a terminal 1,3-butadiyne moiety [9]. 

In further studies relevant to the mechanism of the Mitsunobu reaction, the reaction of diphenylphosphine (40) with di-isopropyl azodicarboxylate (41) was found to give a mixture of products one of which was assigned structure (44) formed via (42) and (43). The reaction of trico-ordinate phosphorus compounds with ortho-quinones,p-ketoalkenes and p-ketoimines is also a well-established source of pentaco-ordinate phosphorus compounds but in some cases the dipolar ion structure is more stable. Thus the reaction of (4Sab) with (46) produced the dipolar ion structures (47ab) but on the other hand, reaction of (45b) with the quinone imine (48) produced what appeared to be an equilibrium mixture of (49) and the pentaco-ordinate structure (50). The 1,3,2-X o -diazaphospholenes (Slab) have proved to be useful synthetic reagents in that on hydrolysis they yield the bis-hydroxylamine (52) which reacts with benzaldehyde to form the imidazoline (53). ...

CF, N 0 PCls O N(CFs) CFj CF,. Further work is in progress. tit is not necessary to isolate the bis-hydroxylamine prior to the oxidation stage. On one occasion a volatile yellow liquid was produced in the oxidation step, and this exploded violently when attempts were made to separate it from the bis-nitroxide removal of chloride ion from the hydrolysate as silver chloride eliminates this problem.
