Are Chelate Rings Aromatic? Calculations of Magnetic Properties of Acetylacetonato and o-Benzoquinonediimine Chelate Rings
(American Chemical Society (ACS), 2007)
The aromaticity of the chelate rings of acetylacetonato (acac) and o-benzoquinonediimine (bqdi) ligands was
investigated theoretically by calculating nucleus-independent chemical shifts (NICS). The calculations were ...
Organocatalyzed cyclizations of π-allylpalladium complexes: A new method for the construction of five- and six-membered rings
(American Chemical Society (ACS), 2007)
Synergic combination of organotransition metal catalysis and organocatalysis allows, for the first time, the Tsuji-Trost cyclization of aldehydes. A catalytic asymmetric variant of the reaction is also possible.
Distribution and fractionation of heavy metals in the Tisa (Tisza) River sediments
(Springer Heidelberg, Heidelberg, 2007)
Introduction. In this work, sediments of the River Tisa (Tisza) are studied to assess their environmental pollution levels for some major heavy metals, as well as to predict the investigated elements' mobility on the basis ...
The qualitative electrochemical determination of clarithromycin and spectroscopic detection of its structural changes at gold electrode
(Elsevier, 2007)
The aim of the present study was the qualitative determination of the pure clarithromycin using a gold electrode in neutral electrolyte by cyclic linear sweep voltammetry. It was shown that in the range of -1.2 V to 1.0 V ...
