Аннотация: The reaction of 2-chloro-3,5-dinitropyridine with two equivalents of KN3 in the presence of ROH results in stable Meisenheimer-type -adducts of 4,6-dinitrotetra-zolo[1,5-a]pyridine with RO– anions (R = H, Alk, Ph). The mechanism of -complex formation was suggested. The structure of the -adduct with R = Me was established by IR and NMR spectroscopy and by X-ray diffraction analysis.

Аннотация: A method was proposed for estimating the possibility of cyclization of adducts of resorcinol with pyrimidines to form oxadiazocines based on the conformational criterion and analysis of charges on the C(5) atom of the pyrimidine ring and on the H atom of the hydroxy group of the resulting adducts. A series of new derivatives of 4,5-dihydro-11H-5,11-methanobenzo[g]azolo[1,3,5]oxadiazocines were synthesized.

POLYFLUORO-2,3-EPOXYALKANES -- THIOUREA -- THIOSEMICARBAZIDE
Аннотация: Reactions of polyfluoro-2,3-epoxyalkanes with thiourea and thiosemicarbazide afforded 2-amino-4-hydroxy-4,5-di(polyfluoroalkyl)-5-fluoro-1,3-thiazolines and 2-hydrazino-4-hydroxy-4,5-di(polyfluoroalkyl)-5-fluoro-1,3-thiazolines respectively. Unsymmetrical oxiranes furnish mixtures of regioisomeric heterocyclic compounds, and the epoxy cycle is predominantly cleaved from the side of bulkier fluoroalkyl group. The reactions of E-oxiranes are stereospecific and provide 1,3-thiazolines in the E-form. The structure of compounds obtained was confirmed by IR, 19F, 1H, and 13C NMR spectroscopy, by mass spectra and chemical transformations. E-isomers of 2-amino-4-hydroxy-4,5-bis(trifluoromethyl)-5-fluoro-1,3-thiazoline and 2-amino-5-heptafluoropropyl-4-hydroxy-4-trifluoromethyl-5-fluoro-1,3-thiazoline were subjected to X-ray diffraction analysis.

Аннотация: Polyfluorinated 1,3-diketones containing carbocycles react with aldehydes under Lewis-acid catalysis and also with dimethylformamide-dimetylacetal without catalysis, yielding exclusively (E)-configured condensation products involving the methylene group of the carbocycle. Novel trifluoromethylated chromenes are prepared from 2-trifluoroacetylcycloalkanones and salicylaldehyde. The structures of two new compounds, 2-(E)-benzylidene-6-trifluoroacetylcyclohexanone and 4-trifluoroacetyl-2,3-dihydro-1H-xantene, are confirmed by X-ray structure analysis.

SILVER-POLYMETALLIC DEPOSIT -- CARBON -- METASOMATIC TRANSFORMATIONS -- REGIONAL MAGMATISM
Аннотация: Products of the hydrothermal alteration of rocks and vertical zonality at the Kanimansur silver-polymetallic deposit (Tadjikistan) have been studied. On the basis of these studies, physicocochemical conditions of metasomatism and ore formation were reviewed. Condensed carbonaceous matter in wall rock metasomatites and ores were found and carbon isotopic composition of this carbonaceous matter and composition of gases in open pores in rocks of the deposit were analyzed. As a result of geological observations, analysis of mineral parageneses, compositions of minerals, and chemistry of wall rock alteration, the following four stages of the hydrothermal process were distinguished: autometasomatic, propylitic, preore chlorite-sericite, and synore. Mineral geothermometers were used to estimate the temperatures of metasomatism, which varied within the range 200-250°C for all stages except for the autometasomatic stage (450-500°C). The formation of unhydrated light micas, quartz, and highly ferruginuous chlorites was related to acid preore metasomatism. The stability of these chlorites testifies to a slight increase in the acidity of solutions during the preore stage (pH not less than 3.5). The wall rock metasomatites and sulfide ores are characterized by a relatively rare occurrence of pyrite due to a low activity of the sulfide sulfur during hydrothermal alterations (logaS2 = -7...-10). The low activity of the sulfide sulfur is confirmed by the fact that iron is tied in a highly ferruginuous chlorite. At upper ore levels, even zinc is tied in chlorite. This testifies to a much greater aS2 /aO2 value. Judging by the participation of carbonaceous matter in the process, ore components were deposited due to a local increase in the alkalinity at the ore-forming stage and oxidation of reduced fluids. The established features of metasomatic transformations, are related to particulars of the regional magmatism.????

Аннотация: The 2-acylcycloalkanones 1a-g and 3a-c, possessing a polyfluoroalkyl group, react with hydroxylamine regio- and stereoselectively to yield 4,5-dihydroisoxazol-5-ols 2a-g and 4a-c, respectively, i.e., products of N-addition to the oxo group at the cycloalkane ring (Schemes 1 and 2). The products 2 and 4 can be dehydrated under drastic conditions only (Schemes 3 and 4). The structure of one of the 4,5-dihydroisoxazol-5-ols was confirmed by X-ray crystal-structure analysis

Аннотация: Study of the Khitoostrov, Varatsk, and other corundum occurrences in kyanite-garnet-biotite plagiogneisses of the Chupa section (Belomorian Mobile Belt) has revealed their association with products of low-alkaline Ca-Na metasomatism characterized by high PT conditions. Similar corundum-bearing rocks, which were also presumably formed during subalkaline metasomatism, are known in Tanzania, India, the United States, and other countries. This paper presents the first results of analysis of the corundum-forming Ca-Na metasomatism.
