Studies of the complexation reactions of polyether ionophore antibiotics monensin A and lasalocid A with lead(II), zinc, calcium and sodium cations.
(2000)
Lead-ionophore complexes of the form PbLX and PbL2 (L = monensin A or lasalocid A; X- = anion) were isolated and characterized by elemental analysis (X = Cl--) and ESI-MS (X = Cl --, NO3, CH3COO--). Changes in the UV-Vis ...
Synthesis and carbon-13 NMR studies of liquid crystals.
(2000)
Eight series of liquid crystals containing an electron-donating group at one end of a conjugated system and an electron-withdrawing group at the other end have been synthesized. The electron-donating group is 4- ...
Dissecting the reaction mechanism of sheep liver 6-phosphogluconate dehydrogenase.
(2000)
In the second part of the research, three additional mutants, S 128A, H 186A and N187A were characterized in the same manner as the K183 mutant enzymes. The decrease in the activity compared to the wild type enzyme is about ...
Investigation of ligand misdirection using the kinetic element effect and the kinetic enthalpy effect.
(2000)
Metal complexes were synthesized with the atropisomeric dabp. X-ray crystal structures were solved for [Ru(bipy)2(dabp)]2+ and [(eta6-C6H6)Ru(dabp)(Cl)]+. Only one diastereomer was observed for [Ru(bipy)2(dabp)] 2+ in the ...
Tuning the frontier orbital character of iron-thiolate complexes.
(2000)
Another part of this work describes the solvatochromatic effect of CpFe(CO) 2(SC6H5) dissolved in different solvents. A blue shift in the UV-vis spectra occurs as CpFe(CO)2(SC6H 5) is solvated in more polar solvents, which ...
Mechanisms of electrophilic aromatic substitution reactions of (eta('6)-arene)molybdenum(phosphine)(, 3) complexes.
(2000)
The mechanism of protonation of (eta6-C6H 6)Mo(TRIPOD) (1) (TRIPOD = tris(1,1,1-diphenylphosphinoethyl)methyl ethane) to give [(eta6-C6H6)MoH(TRIPOD)] + was reported to involve a cyclohexadienyl intermediate. In this ...
A fixed-bed catalytic microreactor with repetitive injection gas chromatographic/mass spectrometric analysis.
(2000)
The work presented here describes the development of a fixed bed catalytic microreactor capable of repetitive injection gas chromatographic analysis of microreactor effluent. The design of our fixed bed microreactor ...
