The photoreactions of 1,4-diphenyl-1,3-butadienes (DPB) fused with a bicyclo[2.2.1]heptano ring under direct irradiation were examined in solution at room temperature and in organic glass at liquid nitrogen temperature. Photocyclization yielding a phenylnaphthalene compound was shown to be preceded by facile E,E to E,Z photoisomerization. The reverse E,Z to… (More)
Irradiation of ethyl cis-o-fluorocinnamate and related compounds in organic glass led to two HT-isomerization processes that exhibit a strong preference at C-beta than at C-alpha as shown by low temperature UV absorption spectroscopy and supported by ab initio calculations.
