Аннотация: Reactions of 7-(X)-substituted ethyl 1-amino-4-oxo-1,4-dihydroquinoline-3-carboxilates (1a-c; X=F, Cl and 4-methylpiperazin-1-yl) with mono- and di-ketones have been studied. Treatment of 1a; X=F with cyclohexanone and cyclopentanone in acetic acid resulted in the corresponding azomethynes

Аннотация: The oxidation of 1-amino-5,6-difluorobenzotriazole with Pb(OAc)4 in dry CH2Cl2 afforded 4,5-difluoro-1,2-dehydrobenzene, a new active intermediate, which can be used in situ for the synthesis of fluorinated carbo- and heterocyclic compounds via cycloaddition reactions.

Аннотация: The reactions of 2,3-dichloro- and 3-chloro-1-ethyl-2-morpholinopyrazinium tetrafluoroborates with compounds containing the active methylene group were studied. The reactions with malonodinitrile and cyanoacetic ester afford products of ipso-substitution at position 2, while 1,3-dicarbonyl compounds produce products of tele-substitution of the Cl atom at the C(3) atom due to the attack of a nucleophile to position 6 of the pyrazine cycle

    Formation of polynuclear palladium complexes with the benzimidazole-2-thiolate anion [Electronic resource] / M. O. Talismanova, A. A. Sidorov, G. G. Aleksandrov, V. N. Charushin, S. K.

Аннотация: The reactions of palladium(II) salts with 2-mercaptobenzimidazole (HL) and its 5,6-difluorinated derivative (HLF) were investigated. In the presence of hydrochloric acid, PdCl2 and K2PdCl4 react with HL and HLF in the ethanol—water and acetonitrile—water systems to form the mono-nuclear dicationic complexes [Pd(HL)4]Cl2 (1) and [Pd(LF)4]Cl2 (2). In the absence of HCl, the reactions afford the tetranuclear complex Pd4[(L)2(3-S,N-(L))2(S,N-(L))4] (3). The reaction of triethylamine with an ethanolic solution of 3 leads to degradation of 3 and the formation of the lantern-type dinuclear complex Pd2[2-(L)4] (4), in which the palladium atoms are in the nonequivalent coordination environment, PdN4 and PdS4. The reaction of K2PdCl4 with HL or HLF in the THF—water or acetonitrile—water systems (for the reaction with HLF) in the presence of Et3N produces the lantern-type dinuclear complexes Pd2[(?S,N-(L3))4] and Pd2[(S,N)(LF))4] (5), in which the metal atoms are in the equivalent coordination environment (cis-PdN2S2)

Аннотация: Complex [CoCl(L)]2(Cl)2 (L = 8-(2-butylthioethyl)oxyquinoline) is studied by X-ray diffraction analysis. The empirical formula of the compound is C30H34Cl4Co2N2O2S2, the crystals are monoclinic, a = 9.9382(13) A, b = 11.9097(8) A, c = 14.5715(11) A = 102.511(9)°, Z = 2, space group P21/c. The complex is dimeric with bridging chlorine atoms, and the heterocyclic ligand L is tridentate-cyclic

1,2,4-TRIAZINES -- TRIETHYLOXONIUM TETRAFLUOROBORATE -- DIELS-ALDER REACTIONS
Аннотация: Quaternization of 3-(3-butynylthio) and 3-(4-pentynyltio) substituted 1,2,4-triazines with triethyloxonium tetrafluoroborate in CH2Cl2 at room temperature occurs exclusively at N-1 yielding 3-alkynylthio-1-ethyl-1,2,4-triazinium salts, as unequivocally shown by the 13C NMR and X-ray crystallographic data. 3-Alkynylthio-1-ethyl-5-phenyl-1,2,4-triazinium salts undergo the intramolecular Diels-Alder reaction into the corresponding thieno [2,3-b]- and thiopyrano [2,3-b]pyridines under considerably milder conditions than the corresponding neutral 1,2,4-triazines.
