A new version of the Mannich reaction involving amino alcohols (3-aminopropan-1-ol and aminoethanol) was developed. These compounds react with formaldehyde and CH or NH acids to give N-substituted tetrahydro-1,3-oxazines or oxazolidines. 相似文献

Thermodecomposition of 3,5- and 3,6-di-tert-butyl-o-benzoquinone complexes of Cu, Fe, Co, Cr, Mo, and W has been investigated in the solid phase by the thermogravimetric method. The relative stability of a series of complexes has been determined from the temperatures at which their decomposition begins. Detachment of a neutral electron-donor ligand takes place in the first stage. Detachment of ano-quinone ligand and decomposition of theo-benzoquinone formed occur in the next stage. Thermodecomposition of Fe, Co, Cr, Mo, and W complexes gives oxides or carbides, while copper complexes decompose to pure metal.Translated fromIzvestiya Akademii Nauk.

The reactions of HNO3 with tetrahydro-1,3-oxazines 1a—c produced by aminomethylation of diketopiperazine, isatin, and succinimide, respectively, afforded nitrates of amino alcohols [RCH2NH2(CH2)3ONO2]+NO3
– (4a—c) whose subsequent N-nitrosation (NaNO2, AcOH) gave nitrates of N-nitrosoamino alcohols RCH2N(NO)(CH2)3ONO2 (5a—c). The structures of compound 5b,c were established by X-ray diffraction analysis. 相似文献

The reactions of isatin, benzotriazole, and succinimide with formaldehyde and methylamine yield monoamines RCH2N(Me)CH2R and methylenediamines RCH2N(Me)CH2N(Me)CH2R. The use of ethylenediamine as the amino component affords N,N"-disubstituted imidazolidines, while the reactions with 3-aminopropan-1-ol give N-substituted tetrahydro-1,3-oxazines. RCH2NBui
2 was obtained from succinimide, formaldehyde, and diisobutylamine. Nitrosative cleavage of the amines obtained was studied; it was shown that monoamines and methylenediamines give N-nitrosoamines RCH2N(NO)Me, which were structurally characterized by X-ray diffraction analysis. RCH2NBui
2 affords diisobutylnitrosamine, while imidazolidines transform into dinitroso compounds RCH2N(NO)CH2CH2N(NO)CH2R. 相似文献

We synthesized a number of derivatives of 1,2,3-benzotriazole, 1,2,4-triazole, and oxazolidine-2-one derivatives, among which
compounds suppressing the growth of the tumor cells HeLa and H1299 were revealed. The studies of the effect of these compounds
on the cell cycle and activity of caspase dependent degradation of poly(ADP-ribose) polymerase showed that these compounds
at the IC50 doses exhibit cytostatic effect on tumor cells. In the MCF7 cells, these compounds induce an increase in expression of the
tumor suppressor p53. 相似文献

The new family of Lewis base free hydrido complexes of rare-earth metals supported by guanidinate ligands [{Ln{(Me3Si)2NC(NiPr)2}2(mu-H)}2] (Ln = Y, Nd, Sm, Gd, Yb) was synthesized and structurally characterized. Single-crystal X-ray and solution NMR studies revealed that these complexes are dimeric in both solid state and in [D6]benzene. The dimeric hydrido complexes can adopt eclipsed (Nd, Sm, Gd) or staggered (Y, Yb, Lu) conformations depending on the metal-atom size. Catalytic activity of these [{Ln{(Me3Si)2NC(NiPr)2}2(mu-H)}2] complexes in the polymerization of ethylene, propylene, and styrene has been investigated. Complexes of Sm and Y have high catalytic activity in ethylene polymerization (1268 and 442 g mmol(-1) atm(-1) h(-1), respectively). 相似文献

The oxidation of bis(triethylgermyl)mercury by oxygen in the presence of tert-butyl alcohol has been investigated. It has been shown that the dependence of the rate of oxidation on the value of n 1 for tert-butyl alcohol within the range n = 0–12 is similar to that for unassociated ligand-catalysts. On increasing n further (from 12 to 60) increasing association of the alcohol causes a drastic increase in the reaction rate relative to the increase in n due to the higher catalytic activity of the high molecular weight associated species. 相似文献

Methods were developed for the synthesis of 6-azido-2,4-bis(2,2,2-trinitroethylamino)- 1,3,5-triazine and its N-nitro derivatives (6-azido-2,4-bis(2,2,2-trinitroethyl)nitramino-1,3,5-triazine and 6-azido-2-(2,2,2-trinitroethylamino)-4-(2,2,2-trinitroethyl)nitramino-1,3,5-triazine) containing combinations of azido, trinitroethyl, and nitramine groups. These compounds are of interest as components of energetic composites. The molecular and crystal structures of 6-azido-2,4-bis(2,2,2-trinitroethylamino)-1,3,5-triazine and 6-azido-2,4-bis(2,2,2-trinitroethyl) nitramino-1,3,5-triazine were studied by X-ray diffraction and NMR spectroscopy. 相似文献
