Abstract
The photolysis kinetics of 4,4’-diazidostilbene stereoisomers in a polymeric matrix (polystyrene films) were studied by the techniques of IR and UV spectroscopy, thin-layer chromatography, and spot test analysis, and primary and secondary amines were determined as the photolysis products, their yield being dependent on the type of stereoisomer. It was shown that, in addition to degradation of the azido group and reactions of the produced nitrenes, stereoisomerization (trans-cis) takes place in the photolysis. As a polystyrene film is formed, the cis-stereoisomers converts into the trans-form
