Abstract

The trans–cis- and cis–trans-isomerization of styryl derivatives of heterocyclic N-oxides in acetonitrile and ethanol is studied. The isomerization quantum yields and spectral characteristics of the cis-form of the investigated N-oxides are determined. No thermally induced cis–trans-conversion is detected.
