Photoisomerization in an analogous set of ruthenium sulfoxide complexes
摘要:
Complexes of the type [Ru(bpy)(2)(OSOBnR)](PF6) where bpy is 2,2'-bipyridine and OSOBnR is a 4-substituted benzylsulfinylbenzoate with R = NO2, F, Cl, H, CH3, CF3 and OCH3, have been prepared and investigated by H-1 NMR spectroscopy, cyclic voltammetry and UV-vis spectroscopy. Despite the distance of the R group from ruthenium, the Ru3+/2+ reduction potential and charge transfer absorption maximum vary predictably with the electron withdrawing nature of the group.

synthesized as anticonvulsant agents. Conformational analysis and superimposition of energy minima conformers of the designed molecules on estazolam, a known benzodiazepinereceptoragonist, revealed that the main proposed benzodiazepinepharmacophores were well matched. Electroshock and pentylenetetrazole-induced lethal convulsion tests showed that the introduction of an amino group in position 2 of 1
