Preparation of Sterically Congested 1,9-Disubstituted Dibenzoselenophenes by Ligand Coupling Reactions and Formation of New Dithia and Diselena Dications on Chemical and Electrochemical Oxidations

Article abstract of DOI:10.1246/cl.1992.675

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.
