                                    A simple one pot synthetic method of a series of 4,5-alkylenedichalcogeno-substituted 1,3-diselenole-2-selones by successive treatments of trimethylsilylacetylene with butyllithium, selenium, carbon diselenide, and finally alpha,omega-bis(chalcogenocyanato)alkanes is described.
