Article abstract of DOI:10.1246/cl.1998.513

Alkeneselenolate and alkenetellurolate ions were generated by treating ketone p-toluenesulfonylhydrazones possessing an α-methylene or an α-methine group with t-BuOK and elemental selenium or tellurium, respectively, at 110-150°C, and were converted into dialkenyl dichalcogenides by aerobic oxidation.
