Photoisomerization of 2,4,4,6-tetraaryl-4H-selenopyrans: A new heterocyclic ring contraction

The UV illumination of title compounds 3a,b in acetonitrile solutions leads to corresponding five-membered ring isomers 4a,b, probably, via open-ring intermediates, whereas the photocolouration was observed in the solid state.

Substituted 2,4,4,6-tetraphenyl-4H-selenopyrans: Preparation, photocolouration and 4H-selenopyran ring geometry; an X-ray and DFT calculation study

1,5-Diaryl-3,3-diphenylpentane-1,5-diones 3a-d react with Al2Se3-HCl-AcOH reagent to give the 2,6-diaryl-4,4-diphenyl-4H-selenopyrans 4a-d in satisfactory yields while the same procedure starting from 1,5-diketone 5 affords small amo
