Reaction of S,S′-dimethyl-N-nitroimidodithiocarbonate with alkali in aqueous-alcoholic solution results in salts of S-methyl-N-nitrothiocarbamate. In anhydrous ethanol a salt of nitrouretane is obtained. By the reaction of S-methyl-N-nitrothiocarbamate salts with hydrazine 4-nitrosemicarbazide salts were prepared.

PrimaryN-nitrosulfamides readily undergo addition to acrolein and vinyl ketones to yieldN-γ-oxoalkyl-N-nitrosulfamides. The presence of a second substituent at the double bond hinders the reaction.N-Nitrourethane reacts with activated carbonyl compounds and α-nitroolefins.

The nitrogen acids RC(O)NHNO2, N-nitroamide, R = CH3 (1), C2H5 (2) and N-nitrocarbamate, R′OC(O)NHNO2, R′ = CH3 (3), C2H5 (4) are a class of primary N-nitrocarboxamide compounds that oxidatively add to trans-Ir(I)(Cl)(N2)(PPh3)2 to give six-coordinate Ir(III)(η2-(NO2)-nitrogen acid)(H)(Cl)(PPh3)2 complexes 5–8. Unexpected fluxional behavior of the complexes in solution is observed by 1H NMR spectroscopy
硝酸RC(O)NHNO 2,N-硝基酰胺,R = CH 3(1),C 2 H 5(2)和N-硝基氨基甲酸酯,R'OC(O)NHNO 2,R'= CH 3(3),C 2 H 5(4)是一类主要的N-硝基羧酰胺化合物,可氧化添加到反式-Ir (I)(Cl)(N 2)(PPh 3)2中,得到六配位的Ir (III)( η 2 - (NO 2) -氮酸)(H)(Cl)的(PPH 3)2个建筑群5 – 8。通过1 H NMR光谱观察到了络合物在溶液中的意外通量行为。还使用31 P和1 H NMR和溶液IR光谱仪观察和监测了氧化加成反应的反应中间体。络合物5与三氟甲磺酸甲酯在CH 3 CN中反应,从净损失的硝酸根阴离子产生双(乙腈)络合物(9)。P(CH 3)2 Ph与5反应生成膦取代的P(CH 3)2 Ph加成异构体(10)。5与CO的反应性研究给出了亚稳态的CO加合物异构体11,该异构体在溶液中长时间放置会失去CO。

New energy-rich derivatives of 2-nitroguanidine were obtained. The synthesis was based on the reaction of 1-chloromethyl-2-nitroguanidine, which was obtained by chlorination of 1-hydroxymethyl-2-nitroguanidine with sodium azide or salts of N-nitramines. The synthesized compounds can be of interest as potential components of both composite solid propellants and explosive compositions.
