## Abstract Epoxidation of (__Z__)โ3โarylideneโ1โthioflavanโ4โones (**1**) yielded __trans,cis__ (**2**) and __trans,trans__ (**3**) isomers. The structure and signal assignments were elucidated by extensive application of oneโ and twoโdimensional ^1^H and ^13^C NMR spectroscopy. The conformational
The reaction of carbon tetrachloride with zeolites exchanged with alkali metal ions was investigated by means of in situ infrared and multinuclear magnetic resonance spectroscopy. Phosgene as reaction intermediate was proven; its formation is influenced by the temperature over the different ion-exch
