SYNTHESIS -- N,N-DIPHENYLGUANIDINE -- AMINOMETHYLIDENE
Аннотация: A series of [(2-dimethylamino)ethylamino]methylidene-1,3-dicarbonyl compounds was synthesized for the first time starting from the corresponding 2-ethoxymethylidene derivatives and N,N-dimethylethylenediamine. It was shown that further alkylation of aminomethylidene derivatives with methyl iodide occurs regioselectively at the tertiary nitrogen atom. Quaternization products obtained exhibit high corrosion inhibition of mild steel in hydrochloric acid medium

CHITOSAN -- PHYSICAL-CHEMICAL PROPERTIES -- PYRIDYL DERIVATIVE
Аннотация: Here we report on the method of synthesis in gel of a new heterocyclic aminopolymer-N-2-(4-pyridyl)ethylchitosan (4-PEC) via direct addition of 4-vinylpyridine to chitosan that yields a derivative with the substitution degree (DS) up to 0.8. The comparison of reactivity, thermal, spectroscopic, and sorption properties of a new derivative and its isomer N-2-(2-pyridyl)ethylchitosan (2-PEC) is presented. 2-PEC has higher sorption capacity and forms more stable chelates with [PdCl4]2- and [PtCl6]2- ions than 4-PEC, but the latter shows higher selectivity to noble metals ions in the presence of Cl- ions. A gradual increase of the sorption capacities and the affinity coefficient for Cu2+ and Ni2+ in the row chitosan<4-PEC<2-PEC was related to the increase of electron donor nitrogen atoms content and chelating properties of 2-PEC. A nearly negligible increase of the 4-PEC sorption capacity for Ag+, as compared to plain chitosan, was suggested to be dependent on the difference in complexation models for 2-PEC and 4-PEC derivatives. The density functional theory (DFT) calculations have shown that the "pendant" model of the complex with Ag(I) is energetically favorable only for 2-PEC derivative, while in cases of chitosan and 4-PEC only "bridge" complexes can be formed that results in lower sorption capacity

AZIDES -- CYCLOADDITION -- NITROGEN HETEROCYCLES
Аннотация: The reactions of β-azolylenamines 1 with sulfonyl azides 2 in acetonitrile furnished 1H-4-(azol-5-yl)-1,2,3-triazoles 3 in yields of 52-93%. β-Benzoylenaminones and β-nitroenamine of type 1 also reacted with tosyl azide to form the same type of products 3, proving the generality and efficiency of the method for the synthesis of N-unsubstituted 1,2,3-triazoles. On the other hand, the reactions of 3-(1-aryl-1,2,3-triazol-5-yl)enamines with tosyl azide in the absence of a solvent afforded a mixture of (E)-1-dimethylamino-2-tosylaminoethenes 5 and N,N-dimethyl-N′- tosylformamidine 6 in yields of 40-50 and 20%, respectively. The formation of a variety of compounds from the reactions of enamines 1 with sulfonyl azides 2 is rationalized by the various possible transformations of the intermediate 5-dimethylamino-1,2,3-triazolines

Аннотация: Novel conjugates of purine and 2-aminopurine linked with heterocyclic amines, including chiral derivatives of 3,4-dihydro- 2H-[1,4]benzoxazine, 3,4-dihydro-2H-[1,4]benzothiazine and 1,2,3,4-tetrahydroquinoline, by 6-aminohexanoyl fragment at the 6-position of purine moiety were obtained. For this purpose, replacement of the chlorine atom in 2-amino-6-chloropurine or 6-chloropurine by direct nucleophilic substitution reaction with 6-aminohexanamides or the coupling of 6-(purin-6-ylamino)-6- hexanoic acid with nitrogen heterocycles were used.

NITROGEN HETEROCYCLES -- FLUORINE -- OXYGEN HETEROCYCLES
Аннотация: New synthetic routes to trifluoromethylated N-heterocycles based on condensations of 2-methoxy-2-methyl-5-(trifluoromethyl)furan-3(2H)-one with bifunctional N-nucleophiles are described. For the first time, trifluoromethyl-containing pyrazoles, pyrazolines and isoxazolines bearing hydrazone or oxime groups could be obtained by a one-pot strategy based on reactions of 5-(trifluoromethyl)furan-3(2H)-one with two equivalents of the corresponding hydrazines or hydroxylamine in the presence of an acid. The interaction of furan-3(2H)-one with ureas proceeded under mild conditions to furnish 1H-furo[2,3-d]imidazol-2(3H)-one derivatives in good yield. Further, a trifluoromethyl-containing quinoxaline derivative was obtained by condensation of furan-3(2H)-one with ortho-phenylenediamine.

Reactions of 4-(3-ethynyl-phenylamino)-1,1,1-trifluoro-pentyl-3-en-2-one with Cu(II) acetate or nanosized powder of copper or its oxides led to the respective chelate complex. The structure of (Z)-1,1,2,2-tetrafluoro-5-(2-propynylamino)-4-hexen-3-one and a copper complex of 4-(3-etinilphenylamino)-1,1,1-trifluoropenta-3-en-2-one was determined by XRD

THERMAL STABILITY -- THIOCARBAMOYLATED POLYSILOXANES -- SILOXANE MATRIX
Аннотация: The thermal stability of the unmodified, aminated, and thiocarbamoylated polysiloxanes has been studied. The siloxane matrix is stable in the temperature range up to 800°C. For the first time, mass spectrometry has been applied to the analysis of the composition of the gaseous products of thermal decomposition of the studied polysiloxanes. It has been shown that, in the process of thermal decomposition, the terminal functional groups are detached and oxidized. Water, ammonia, nitrogen, carbon, and sulfur (in the case of thiourea-modified sorbent) oxides are formed predominantly. The quantitative removal of functional groups during heating up to 800°C has been confirmed by IR spectroscopy. A mechanism of thermal decomposition of polysiloxane xerogels has been proposed. It has been found that adsorption of platinum increases the thermal stability of the samples

Аннотация: The basicity of some 1,2,4-triazine 4-oxides was estimated on a quantitative level, and their probable protonation patterns were ascertained. The dissociation constants of mono- and diprotonated 3-R-6-phenyl-1,2,4-triazine 4-oxides in aqueous buffer solutions and aqueous sulfuric acid solutions were determined (6-phenyl-1,2,4-triazine 4-oxide: pKBH + = 1.1, pKBH 2+ = - 6.02). According to the results of DFT calculations (B3LYP/6-311**) and spectral data, first protonation of 1,2,4-triazine 4-oxides involves the N1 nitrogen atom, and the second proton adds to the N-oxide oxygen a
