Аннотация: Fluorinated enaminoketones, a new type of ligands, bearing two independent coordination centers (polyether's and fluorinated enaminoketones fragments) have been obtained. The crystal structure of the Cu(II) complex of 1,5-bis-[2-(4`,4`,4`-trifluoro-1`-methyl-3`oxo-but-1`-enylamino)-phenoxy]-3-oxapentane (10) has been elucidated by X-ray crystallography. The results obtained show that the complex 10 consists of two crystallographically independent molecules C26H24CuF6N2O5 (A and B), and the metal atom in the complex 10 has four-coordinated arrangement, as a polyhedron with a distorted square with two nitrogen and two oxygen atoms located in corners.

TRIAZOLIUM -- SYNTHESIS -- CARBONYL GROUP
Аннотация: Intramolecular cyclization of 1-amino-3-phenacyl-4-carbohydrazido-1,2,3-triazolium-5-olates has been shown to take place via selective interaction of the carbonyl group with the terminal amino function of the hydrazido group to form a 1,2,5-triazepine ring. Minor products, resulting from the interaction of the ?-nitrogen atom of the hydrazido group with the carbonyl function, having a N-amino-pyridazine structure were also detected and isolated. A general method for the synthesis of novel mesoionic 2-amino-7-aryl-4-oxo-2,4,5,8-tetrahydro[1,2,3]triazolo[5,1-d][1,2,5]triazepin-9-ium-3-olates was developed.

HYDRAZINES -- MOLECULAR STRUCTURE -- ISOMERIC PYRAZOLES;
Аннотация: The reaction between 2-trifluoroacetylcycloalkanones and methylhydrazine or phenylhydrazine exclusively yields 3-CF3-pyrazoles. When the chain length of the polyfluorinated substituent in RFC(O) group increases, 5-RF-pyrazoles are isolated. The reaction of 2-trifluoroacetylcyclohexanone with 2-hydrazinopyradine gives 5-hydroxypyrazoline, an intermediate in the formation of 5-CF3-pyrazoles. The regiochemistry of the condensation is probably controlled by the nucleophilicity of the terminal nitrogen in the mono substituted hydrazines and by the steric requirements of the RF group in the 1,3-diketones. Polymethylene chain containing pyrazoles obtained from the 1,3-diketones in question and hydrazine prefer the 3-RF tautomeric form, irrespective of carbocyclic ring size and polyfluoroalkyl group chain length.

AROMATIC SUBSTITUTION -- NUCLEOPHILIC SUBSTITUTION -- NITROGEN HETEROCYCLES
Аннотация: The 3,6-diaryl-1,2,4-triazine 4-oxides 1a-e undergo a nucleophilic substitution of hydrogen with the -halomethyl aryl sulfones 2, 3 and 7 by two alternative pathways: vicarious nucleophilic substitution (VNS) and/or an intramolecular deoxygenative process. The former pathway is found to dominate in the reaction of 1 with bromomethyl tolyl sulfone (7) yielding the 5-tosylmethyl-1,2,4-triazine 4-oxides 6, while the reaction with the chloromethyl aryl sulfones 2 and 3 leads to the 5-arylsulfonylchloromethyl-1,2,4-triazines 4 and 5, respectively, as the products of deoxygenative substitution. The reaction of 6-phenyl-1,2,4-triazine 4-oxide (1f) with the chloromethyl aryl sulfones 2 and 3 proceeds differently. At low temperature (-75 C) the products of the VNS reaction at position 5 (6f and 12f) are formed. At room temperature the 7-chloro-1-hydroxy-3-phenyl-7-(arylsulfonyl)-1,4,5-triazahepta-1,3,6-trienes 10f and 11f are obtained by addition of the carbanions 2 and 3 in the 3-position, followed by the ring opening of the resulting adduct. © Wiley-VCH Verlag GmbH, 69451 Weinheim, Germany, 2002)????????

Аннотация: Internal perfluoroolefin oxides reacted with urea to give, depending on the solvent nature, two types of new fluorine-substituted nitrogen-containing heterocycles. 1,5-Bis(perfluoroalkyl)tetraazabicyclo[3.3.0]octane-3,7-diones were formed in dimethyl sulfoxide, N,N-dimethylacetamide, and acetonitrile, while the reaction in dioxane resulted in the formation of unexpected products, 2-amino-5-fluoro-4,5-bis(perfluoroalkyl)-4,5-dihydrooxazol-4-ols, existing mainly as trans isomers. trans Orientation of perfluoroalkyl substituents in these compounds was determined by analysis of 19F-19F spin-spin coupling constants in the 19F NMR spectra. The molecular structure of trans-2-amino-5-fluoro-4,5-bis(trifluoromethyl)-4,5-dihydrooxazol-4-ol was studied by X-ray analysis.

Аннотация: The synthesis of substituted terpyridines via triazine intermediates is described. The intermediates allow the facile introduction of cyano groups, which are converted into amino diacetic acid moieties. Together with the terpyridine nitrogen atoms they shield coordinated europium(III) ions completely from the solvent. The terpyridines may be further functionalized for specific applications using ligands, bromo substituents, and standard transition metal mediated coupling methods. This makes the title compounds valuable intermediates for the preparation of luminescent probes in biochemistry, medicinal diagnostics or materials science.

The reaction of compounds 1a,b with compounds 2 and 3 in the presence of trifluoroacetic acid results in the addition of the dimethylphenoxy group to the unsubstituted C(5) carbon atom of the triazine ring. The reactions of triazinones 6-8 with compounds 1a,b in a mixture of trifluoroacetic acid and organic anhydrides are accompanied by the acylation of the nitrogen atom adjacent to the reaction center and affords bis[(3-R-1-acyl-5-oxo-1,4,5,6-tetrahydro-1,2,4-triazin-6-yl)-2,6-dimethylphenoxy]-3-oxapentane or -3,6-dioxaoctane. The obtained adducts can smoothly be oxidized under mild conditions to form more stable products of nucleophilic hydrogen substitution in the triazine ring. The extraction and transport of Ca2+ and Mg2+ cations through an organic membrane by the compounds synthesized are discussed.
