Аннотация: Atropoisomerism of tertiary 13-amides of chlorin e 6 was studied by the methods of X-ray analysis, 1H NMR spectroscopy, and high performance liquid chromatography on the example of 13-N,N-dimethylamide-15,17-dimethyl ester of chlorin e 6. The spatial structure of the major and minor atropoisomers was established. The possibility of reversible interconversion of the atropoisomers of the studied compound in solution was shown

BACTERIAL DEGRADATION -- CHEMICAL MODIFICATION -- POLYETHYLENE GLYCOLS
Аннотация: Polychlorinated biphenyls (PCBs), also known by the trade name Sovol, are toxic industrial wastes. They have been subjected to chemical treatment by polyethylene glycols (PEGs) and potassium hydroxide. As a result of the interaction of the Sovol with various molecular mass PEGs (MMPEG-4 ∼ 200, MMPEG-22 ∼ 1000), water-soluble mixtures M1 and M2 containing mono(polyethylene glycol)oxy-derivatives (PCB-PEG-4 and PCB-PEG-22), polychlorobiphenylols, and unreacted PCB congeners (PCB 44, PCB 47, PCB 49, PCB 52, and PCB 66) were obtained. It was shown for the first time that mixtures M1 and M2 are susceptible to bacterial degradation without their fractionation. According to the gas-liquid chromatography with flame-ionization and mass-spectrometric detection, the Rhodococcus wratislaviensis KT112-7 strain degraded all of the chemical compounds occurring in the mixtures. In a 5-day experiment, it was found that the KT112-7 strain decomposes mono(polyethylene glycol)oxy-derivatives completely (by 100%) and polychlorobiphenylols and PCB congeners by 90–95% in the M1 and M2 mixtures. The culture medium did not contain transformation products, whereas free chlorine ions were accumulated (72–94% of the maximum possible amount). Thus, the use of the chemical modification and consecutive bacterial degradation provided an effective destruction of technical PCB mixtures with a high content of highly chlorinated congeners

    Bacterial degradation of PCB 70 and its hydroxy derivatives is an environmentally friendly way to destroy pops / T. D. Kir'yanova, D. O. Egorova, T. I. Gorbunova, M. G. Pervova // Bio Web of Conferences : International Scientific and Practical Conference “Innovations, Technological Solutions and Management in Modern Biotechnology and Biomedicine” (ITSM-2022). - Pushchino, 2023. - P09002
Рубрики: ХИМИЧЕСКИЕ НАУКИ
Аннотация: One of the problems of our time is the environmentally safe destruction of polychlorinated biphenyls (PCBs) and their hydroxylated derivatives. The aim of the study was to investigate the features and prospects of the decomposition of PCB 70 (2,5,3',4'-tetrachlorobiphenyl) and hydroxylated chlorobiphenyls derived from it by Rhodococcus wratislaviensis strain CH628. As a result of the application of methods of periodic cultivation, gas chromatography and light spectrometry, it was found that the efficiency of destruction of PCB 70 1 g of cells of strain CH628 was 90 mg PCB/day, and the same indicator for a mixture consisting of hydroxy derivatives obtained from PCB 70 was 56 mg PCB/day. It was shown that the strain uses all components of the mixture of hydroxy-PCB 70 as a growth substrate, but with different degradation rates. When cultivated in a mineral medium with PCB 70 or a mixture of hydroxy-PCB 70, strain CH628 forms biofilms. The analysis of the obtained results shows that the use of the Rhodococcus wratislaviensis CH628 strain will make it possible to develop a technology for the environmentally safe destruction of PCB 70 and hydroxy-PCBs derived from it.

SUZUKI–MIYAURA -- CROSS-COUPLING -- PYRIMIDINES
Аннотация: It has been shown that combination of the Suzuki–Miyaura cross-coupling and nucleophilic aromatic substitution of hydrogen is a versatile method for the synthesis of 4-(thiophen-2-yl)-, 5-(thiophen-2-yl)-, and 4,5-di(thiophen-2-yl) substituted pyrimidines from the commercially available 5-bromopyrimidine. The HSN (AE)- and HSN (AO)-reactions of 5-bromopyrimidine with thiophene and 2-bromothiophene have been studied by gas–liquid chromatography/mass-spectrometry. The structures of intermediate σH-adducts, as well as thiophene-(thiophenyl)pyrimidine and bithiophene-(thiophenyl)pyrimidine dyads have first been established by X-ray crystallography analysis

Uimin, A. E. Ermakov, C. K. Rhee, V. N. Charushin // Russian Journal of General Chemistry. - 2007. - Vol. 77, № 3. - P404-408. - Библиогр. : с. 408 (12 назв.)

Аннотация: Transformations of phenylacetylene and tert-butylacetylene in the presence of copper and copper oxide (Cusub2/subO, CuO) nanopowders prepared by gas-phase condensation of copper in argon were studied. The reaction of phenylacetylene with copper oxide nanopowders having different phase compositions in the absence of a solvent at room temperature resulted in oxidative condensation of phenylacetylene and complex formation of the condensation product. The complex undergoes decomposition by the action of acids, bases, and compounds capable of forming complexes. According to the X-ray diffraction data, one of the products is a new “parquet” modification of diphenyldiacetylene. Under analogous conditions, tert-butylacetylene gave rise to a complex mixture of products among which di- tert-butyldiacetylene was identified by gas chromatography-mass spectrometry. No copper complexes with the tert-butylacetylene condensation products were detected.

Аннотация: Nitration of mono-, di-, and trichlorobiphenyls has been studied. The nitration degree depends on the number of chlorine substituents; one to four nitro groups can be introduced. The conclusions have been confirmed by results of nitration of the "Trikhlorbifenil" technical mixture of polychlorinated biphenyls.

    Mass spectrometry study of the pyrolysis of perfluoroolefin oxides [Electronic resource] / N. D. Kagramanov, A. A. Kutin, N. V. Peschanskii, A. Ya. Zapevalov, L. S.

Рубрики: ХИМИЧЕСКИЕ НАУКИ
Аннотация: The pyrolysis of perfluoroolefin oxides has been studied by gas chromatography/mass spectrometry at 400–700°C, in a current of He (110 dilution, contact time 1 sec). For oxides containing a terminal CF2 group, the sole degradation route is through the elimination of difluorocarbene. Pyrolysis of symmetrical disubstituted oxides results in the elimination of a perfluoroalkylfluorocarbene, which subsequently isomerizes to the corresponding perfluoroolefin. In the pyrolysis of unsymmetric disubstituted oxides the elimination of perfluoroalkylfluorocarbenes occurs by both of the possible routes. Trisubstituted oxides eliminate bis-perfluoroalkylcarbenes. The decomposition of tetrasubstituted oxides proceeds along several directions concurrently
