been prepared by the reaction of 1,4-dibromobutane or 1,5-dibromopentane with potassium chalcogenides. The novelty of the route consists of the use of the hydrazine hydrate–KOH system for the reductive generation of potassium selenide, telluride, diselenide or ditelluride from elemental chalcogens.
