AbstractBis(polyfluoroalkyl) chlorophosphites and polyfluoroalkyl dichlorophosphites react easily with secondary amines (from –40 to –22°C, 1–3 h, CH2Cl2) in the presence or absence of triethylamine to form the corresponding bis(polyfluoroalkyl) diorganylamidophosphites or bis(diorganylamido) polyfluoroalkyl phosphites in the yield of up to 74%. Bi...

AbstractThe V2O5–MoO3–P2O5 (VMPO) catalyst has been prepared in situ by thermal decomposition of vanado-molybdophosphoric acid (PMoV) on TiO2 support at 475°C. The TiO2 supported VMPO catalysts are characterized by FT–IR, XRD, BET surface area, NH3–TPD, and H2–TPR. Morphology of the catalyst has been studied by TEM. The accumulated data indicate de...

AbstractSimplest derivatives of the cotarnine alkaloid, like cotarnone and 1,2-dihydrocotarnine, undergo electrophilic Einhorn acylamidomethylation (with 60–95% yield) and sulfochlorination with chlorosulfonic acid at position 5. At the same time cotarnone and its derivatives undergo additional O-protodemethylation. Using these and some other react...

AbstractRecyclization of furan-2,3-diones acylhydrazones under the action of esters, amides and nitriles of cyanoacetic acids gave the corresponding esters, amides and nitriles of 2-amino-1-R-4-oxo-5- (2-oxo-2-aryl/tert-butylethylidene)-4,5-dihydro-1H-pyrrole-3-carboxylic acids.

AbstractThe nucleophilic addition of benzoselenol occurs regioselectively at the β-carbon of the triple bond of 1,5-disubstituted pent-2-ene-4-yne-1-ones, pent-4-ene-2-yne-1-ones and pent-1-ene-4-yne-3-ones. The resulting selenium-containing conjugated dienones exhibit pronounced cytotoxicity against some tumor cell lines.

AbstractA series of new pyrimidine derivatives, including those containing an azole or azine heterocycle linked through a sulfur atom or a thiomethylene group, was synthesized based on 2-amino-6-methylpyrimidine-4(3H)-thione. The synthesized compounds exhibited a pronounced stimulating effect on plants growth in the range of 43–96% compared to hete...

AbstractThe interaction of Co(NO3)2 and Cu(NO3)2 with hyperbranched polyester containing 7 terminal benzoyl thiocarbamate groups has been studied by IR-Fourier and electron absorption spectroscopy. А new polynuclear complexes of Co(II) and Cu(II) with poly(benzoyl thiocarbamate)-modified hyperbranched polyester have been synthesized. It has been fo...
