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

Аннотация: Groups of congeners and individual congeners of polychlorobiphenyls contributing to the composition of the technical mixture "Sovol" (PCB 60, PCB 64, PCB 70, PCB 74, PCB 97, PCB 101, PCB 105, PCB 110, PCB 118, PCB 138, PCB 149, PCB 156, and PCB 163) were synthesized by the reaction of aryl-aryl coupling. The interaction of the congeners with sodium methoxide was performed and their complete conversion was proved. By means of gas chromatography-mass spectrometry the PCBs methoxy derivatives were identified. The data on the reactivity of the individual polychlorobiphenyl congeners were precised

    Microwave-assisted palladium-catalyzed C–C coupling versus nucleophilic aromatic substitution of hydrogen (SNH) in 5-bromopyrimidine by action of bithiophene and its analogues [Электронный ресурс] / E.

C–H BOND ACTIVATIONS -- PYRIMIDINES -- PALLADIUM
Аннотация: 5-Bromopyrimidine reacts with 2,2′-bithiophene, [2,2′:5′,2″]terthiophene and 2-phenylthiophene in the presence of a palladium catalyst to give 5-(het)aryl substituted pyrimidines due to the palladium-catalyzed aryl–aryl C–C coupling. However 5-bromo-4-(het)aryl-pyrimidines have been prepared from the same starting materials through the SNH-reaction catalyzed by a Lewis acid. Conditions for both types of reactions were optimized. All components of the reaction mixtures, including by-products, have been elucidated by gas–liquid chromatography/mass-spectrometry. Evidence for the structure of 4- and 5-bithiophenyl-substituted pyrimidines has first been obtained by means of X-ray crystallography analysis. Molecular orbital calculations (TDDFT), as well as the redox and optical measurements for all new compounds have also been performed

1,2,4-TRICHLOROBENZENE -- BIPHENYLS -- SOVOL
Аннотация: The reactions of a mixture of 1,2,3- and 1,2,4-trichlorobenzene and polychlorinated biphenyls congeners of the industrial mixture Sovol with neopentyl glycol in the presence of alkali in DMSO medium was studied. In the conditions of nucleophilic substitution the aromatic compounds are converted completely. Using the method of gas chromatography with flame ionization and mass spectrometric detectors the structure of all synthesized compounds was studied and the following series of increasing reactivity of the polychlorinated biphenyls congeners was revealed: tetra- < penta- < hexachlorobiphenyls. The process can serve as a preliminary step of the preparation of industrial waste for the subsequent biological degradation

Аннотация: The suspension polymerization in octafluorobutane, initiated by Ziegler–Natta catalyst system, has been used to synthesize ultra-high molecular weight poly(1-hexene), poly(1-octene), and poly(1-decene) of regular structure with high yields. This technique makes it possible to successfully carry out reactions at close to room temperature, followed by easy isolation of polymer products. The regularity of the structure of the synthesized polymers was proved based on the data of 1H and 13C NMR spectroscopy. Using gel permeation chromatography, data on the molecular weight distribution of polymer molecules were obtained. They indicated that the weighted average mass of the synthesized polymers is many times higher than the mass of polyolefins produced by the classical technique of homogeneous polymerization.

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.
