Sažetak
The photochemistry of styryl substituted monofuran derivatives has been thoroughly investigated [1]. In disubstituted o-divinylbenzenes, compounds 1a-c, the possibility of the intramolecular excimer formation is introduced [2] which resulted in the formation of bicyclo[3.2.1]octadiene structures, cyclophanes and cyclobutanes. Contrary to these results, on the irradiation of the aryl and heteroaryl analogues of 2, 3-distyrylfurans 2a-d different intra- and intermolecular processes have been observed. These hexatriene systems gave stilbenyl-like and phototransposition products. The reaction mechanism will be discussed.
