Аннотация: New tetranuclear Cu(II) complex [Cu4(L)4]·MeCN (1) with 2,6-di(5-trifluoromethyl-1H-pyrazol-3-yl)pyridine (H2L) was synthesized. It has been shown that treatment of 1 with selected aza-ligands (pyridine, 2,2′- and 4,4′-bipyridyl, 2,3,5,6-tetra-(pyridine-2-yl)pyrazine, 2,2′;6′,2″-terpyridine and 1,4-diazabicyclo[2.2.2]octane) leads to formation of other Cu(II) complexes with different nuclearity: [Cu(L)py2] (2), [Cu(L)(2,2′-bpy)] (3), [Cu(L)2(tppz)]·THF (5), [Cu(L)tpy]·C6H5CN (4), {[Cu2(L)2(4,4′-bpy)2]·(C6H5CH3)·MeCN}n (6) and {[Cu(L)DABCO]·2MeCN}n (7). Obtained compounds were characterized by IR spectroscopy, X-ray crystallography data, EPR and SQUID magnetic measurements. --------------------------------------------------------------------------------

Ключевые слова (''Своб.индексиров.''): lithium--enolates--unusual reactions
Аннотация: The present paper describes unusual reactions of lithium enolate of ethyl 4,4,4-trifluoro-3-oxobutanoate with ammonium acetate and 1-aminonaphthalene. These reactions produce 4-amino-2,6-bis(trifluoromethyl)pyridine and 4-trifluoromethyl-2-[(Z)-1,1,1-trifluoroprop-1-en-2-ol-1-yl]benzo[h]quinoline, respectively. The reaction of 1,1,7,7,7-hexafluoroheptane-2,4,6-trione hydrate with 1-naphthylamine gives a mixture of 4-trifluoromethyl-2-[(Z)-1,1,1-trifluoroprop-1-en-2-ol-1-yl]benzo[h]quinoline and N,N′-bis(naphth-1-yl)-2,6-bis(trifluoromethyl)pyridine-4(1H)-imine, respectively

Ключевые слова (''Своб.индексиров.''): electrochemistry--nickel complexes--x-ray diffraction analysis
Аннотация: 2,6-Bis(5-trifluoromethylpyrazol-3-yl)pyridine (H2L) and its mono-, tri-, and tetranuclear NiII complexes were synthesized for the first time. All the obtained compounds were characterized by single-crystal X-ray diffraction analysis. In the complexes, 2,6-bis(5-trifluoromethylpyrazol-3-yl) pyridine exists in the neutral and dianionic forms and exhibits different coordination modes (κ3-, μ2-κ3: κ1-, and μ3-κ3: κ1:κ1). The electrochemical and magnetic properties of all compounds were studied. The tetranuclear NiII complex with the L2- dianion is reduced in two sequential reversible one-electron steps

Ключевые слова (''Своб.индексиров.''): synthesis--nitrogen--terminal c≡c bonds
Аннотация: The reaction of fluorinated lithium 1,3-diketonates with propargylamine hydrochloride and 1,1,1-trifluorpentane-2,4-dione or 1,1,1-trifluoro-4-methoxypent-3-en-2-one with propargylamine and 3-aminophenylacetylene were performed to obtain fluorinated 1,3-enaminones containing at a nitrogen atom substituents with terminal C≡C bonds: (Z)-1,1,1-trifluoro-4-(2-propynylamino)-3-pentene-2-one, (Z)-1,1,2,2-tetrafluoro-5-(2-propynylamino)-4-hexen-3-one, and 4-(3-ethynylphenylamino)-1,1,1-trifluoropentyl-3-en-2-one. Reactions of 4-(3-ethynyl-phenylamino)-1,1,1-trifluoro-pentyl-3-en-2-one with Cu(II) acetate or nanosized powder of copper or its oxides led to the respective chelate complex. The structure of (Z)-1,1,2,2-tetrafluoro-5-(2-propynylamino)-4-hexen-3-one and a copper complex of 4-(3-etinilphenylamino)-1,1,1-trifluoropenta-3-en-2-one was determined by XRD

Заглавие : Heterospin complexes of fluorinated dinuclear Cu(II) and Mn(II) triketonates with nitroxides [Electronic resource]

Аннотация: Dinuclear heterospin complexes of CuII and MnII 1,1,1,7,7,7-hexafluoroheptane-2,4,6-trionates ([Cu2L2] and [Mn2L2], respectively) with nitronyl nitroxides 2-R-4,4,5,5-tetramethyl-4,5-dihydro-1H-imidazole-3-oxide 1-oxyls (NIT-R, R = H, Me, Et, m-C5H4N, m-NCC6H4, p-NCC6H4, PzMe) and the diradical NIT-Pz-(CH2)4-Pz-NIT (Pz is 1,4-pyrazolylene) were synthesized and structurally characterized. In the complexes under study, the CuII atom tends to have the square-pyramidal coordination environment, and the MnII atom is in an octahedral environment. The magnetochemical investigation of the compounds in the temperature range of 2–300 K showed that the antiferromagnetic exchange coupling dominates in the [Cu2L2] molecules, whereas this coupling in [Mn2L2] is manifested in the experimental plot µeff(T) at T 100 K. The magnetic properties of the heterospin complexes of [Cu2L2] with NIT-R are also determined by the intramatrix antiferromagnetic exchange coupling. For the complexes of [Mn2L2] with NIT-R, the coordination mode of the nitroxide plays a decisive role.

Аннотация: Ethyl 1-trifluoromethyl-1-hydroxy-3-oxo-phosphonates, the related (methyl)phosphinates and (phenyl) phosphinates, and phosphine oxides were obtained in good yield via direct phosphonylation of acyltrifluoroacetones with diethyl phosphite, ethyl (methyl) phosphonite, ethyl (phenyl) phosphonite, and diphenylphosphine oxide in the presence of triethyl borate. The subsequent dehydration of the selected phosphonates and phosphinates proceeds smoothly affording previously unknown diethyl 1,2-unsaturated 1-trifluoromethyl-3-oxophosphonates, ethyl 1-trifluoromethyl-3-oxo(methyl)-, and ethyl 1-trifluoromethyl-3-oxo(phenyl) phosphinates in good yields

Ключевые слова (''Своб.индексиров.''): fluorinated 1,3-diketones--acetals--claisen condensation--calcium hydride--3-(polyfluoracyl)pyruvaldehydes--pyrazole-1h-3- carbaldehydes
Аннотация: An efficient approach for the synthesis of 3-(polyfluoroacyl)pyruvaldehydes dimethyl acetals (1,1-dimethoxy-4-polyfluoroalkyl-butan-2,4-dions) from 1,1-dimethoxyacetone and polyfluorinated carboxylic acid esters has been developed. The procedure includes the Claisen type condensation of the starting materials by means of calcium hydride in methanol, followed by isolation of copper complexes of the corresponding diketones and their destroying with disodium EDTA. A simple synthesis of 5(3)-(polyfluoroalkyl)-1H-pyrazole-3(5)-carbaldehydes and their acetals is also presented.
