Copper(II) complexes of usnic acid condensation products and their antibacterial activities
(Marcel Dekker Inc, New York, 1998)
The complexes of Cu(II) and condensation products of usnic acid with the acyl hydrazides of alpha-naphthoic, caprylic and oxamic acid, as well as the-derivative of usnic acid with thiosemicarbazide have been synthesized ...
Sesquiterpene lactones from plant species Centaurea solstitialis L.
(Serbian Chemical Soc, Belgrade, 1998)
The identification of nine known guaianolides, i.e., solstitialin A, its 13-acetate, linichlorin B, cynaropicrin, centaurepensin (chlorohyssopifolin A), 17-epi-centaurepensin, 19-desoxychlorojanerin, 11 beta,13-dihydrode ...
Prediction of the reactive intermediates in alkane activation by tris(pyrazolyl borate)rhodium carbonyl
(Amer Chemical Soc, Washington, 1998)
Two intermediates are observed in the time-resolved IR spectra of the photoinitiated alkane (RH) activation reaction of Tp*Rh(CO)(2) (Tp* = HB-(3,5-dimethylpyrazolyl). Density functional calculations suggest that the first ...
Transition metal complexes with thiosemicarbazide-based ligands .28. Synthesis and x-ray crystal structure of the first phosphorus-bonded thiosemicarbazide complex: [2-(diphenylphosphino)benzaldehyde thiosemicarbazonato(1-)]pyridinenickel(II)-nitrate
(Taylor & Francis Ltd, Abingdon, 1996)
The synthesis and crystal structure analysis of the diamagnetic complex [Ni(L)Py]NO3 (L = the monoanion of the newly synthesized ligand 2-(diphenylphosphino)benzaldehyde thiosemicarbazone) are reported. The complex ...
A convenient synthesis of trifluoromethyl aryl sulfides
(Pergamon-Elsevier Science Ltd, Oxford, 1996)
Trifluoromethyl aryl sulfides are obtained in moderate/good yields by heating potassium trifluoroacetate and aryl disulfides in sulfolane. Copyright (C) 1996 Elsevier Science Ltd
The preparation and characterization of facial and meridional isomers of uns-cis-(ethylenediamine-N,N '-di-3-propionato)cobalt(III) complexes with aliphatic alpha-S-amino acids
(Serbian Chemical Soc, Belgrade, 1998)
A series of several complex compounds, both facial and meridional, of uns-cis-(ethylenediamine-N,N'-di-3-propionato)cobalt(III) complexes with some alpha-S-amino acids, S-alanine, S-valine, S-leucine and S-isoleucine, were ...
The synthesis and in vitro activity of some Delta(7,9(11))-lanostadienes
(Elsevier Science Inc, New York, 1997)
The synthesis of Delta(7,9(11))-lanostadiene derivatives functionalized at C(32) starting from 3 beta-acetoxy-7 alpha,32-epoxylanostan-11-one has been presented. The Delta(7,9(11)) moiety was efficiently introduced in three ...
Synthesis and structure of aqua-2',2'''-(2,6-pyridindiyldiethylidene) dioxamohydrazide-copper(II) hydrate
(Pergamon-Elsevier Science Ltd, Oxford, 1997)
In a template synthesis from copper(II) acetate, 2,6-diacetylpyridine, and semioxamazide (NH2CO CONHNH2), two new copper(II) complexes, [Cu(dapsox)(H2O)]. H2O and [Cu(Hdapsox)(H2O)]ClO4, (where H(2)dapsox = 2',2'''-(2,6- ...
The anisotropic pi-effect of the nitro group in ammine-nitro cobalt(III) complexes
(Pergamon-Elsevier Science Ltd, Oxford, 1997)
The analysis of crystal structures of the series of ammine-nitro cobalt(III) complexes has shown that Co-NO2 bond lengths can be successfully rationalized on the basis of the anisotropic pi-effect of nitro groups. This ...
Comparison of allergenic potentials of timothy (Phleum pratense) pollens from different pollen seasons collected in the Belgrade area
(Munksgaard Int Publ Ltd, Copenhagen, 1997)
We investigated extracts of timothy grass pollen from four seasons (1989, 1990, 1991, and 1994) by protein content, SDS-PAGE, immunoblot, RAST, RAST inhibition, and crossed immunoelectrophoresis. Extract of the pollen from ...
