- Spectral properties and photobehaviour of 2,5-distyrylfuran derivatives
-
Four novel trans,trans-2,5-distyrylfuran derivatives (E,E-X-DStFs, X = Cl, OCH3, N(CH3)2, NO2) have been synthesized and characterized by 1H and 13C NMR and UV-vis spectroscopy. The photoph

- Synthesis of the novel conjugated ω,ω′-diaryl/heteroaryl hexatriene system with the central double bond in a heteroaromatic ring: photochemical transformations of 2,3-divinylfuran derivatives
-
New β,β′-aryl/heteroaryl 2,3-divinylfuran derivatives (9a-d) in which a hexatriene system is a part of heteroaromatic ring have been synthesized and their photochemical properties were investigated. The primary process observed was the isomerization to trans,trans-isomers 9a-d followed by photochemical rearrangement of the furan ring giving the phototransposition products (I-IV). Stilbenes (20, 21) and phenanthrenes (22, 25, and 26), formed as secondary products from the competitive intermolecular cycloadditions, were also observed.
