1,9-Dithia and 1,9-diselena substituents in dibenzochalcogenophenes 1 are in close proximity within the van der Waals S-S and Se-Se contacts and hence have a strong through-space interaction.Photolysis of the compounds 1 with a 400 W high-pressure mercury

Sterically congested 1,9-bis(phenylthio)dibenzoselenophene (4a) and 1,9-bis(phenylseleno)dibenzoselenophene (4b) were prepared.New dithia dication and diselena dication were generated from 4a and 4b, respectively, in concd sulfuric acid.
