Hanusek, Jiří; Sedlák, Miloš
The presented review covers applications (especially medical and pharmaceutical), natural occurrence and the synthesis of quinazolin-2-one, quinazolin-4-one and quinazolin-2, 4-dione derivatives. The reaction mechanisms of the most interesting reactions are also discussed.

Šimůnek, Petr
The structure of ß-enaminones is discussed from three points of view: distribution of electron density and related reactivity towards electrophiles, geometrical isomerism and tautomerism. Geometrical isomerism and tautomerism are discussed from various aspects.

Fiedler, Josef; Pavlík, Ivan; Pavlišta, Martin
Strong-field energy matrices expressed in terms of four d-orbital splitting parametrs (Ds, Dt, Dq, Dr) and two Racah parameteters (B, C) without spin-orbit coupling effects were calculated for the d3 and d4 (C2v) metallocene derivates.

Smička, Aleš; Handlíř, Karel
A set of novel 3-methoxypropyltin (IV) compounds of the general formula (CH3 OCH2 CH2 CH2) SnCl 4-x (x=1-4) was synthesized and characterized. Shape of the coordination polyhedra about central tin atom and character Sn-O interaction are discussed on the basis of multinuclear NMR spectra, IR spectra and X-ray structure determination. Enhanced water solubility of these compounds was observed.
