Abstract

Seven bis‐(1λ^4^,2‐diselenol‐1‐ylium) tetrachloroferrates have been prepared by reaction of 1,3‐diketones or 1,3‐ketoaldehydes with hydrogen selenide and iron(III) chloride in ethanol saturated with hydrogen chloride. They decompose gradually in air. The corresponding 1λ^4^,2‐diselenol‐1‐ylium perchlorates have been prepared by reaction of the tetrachloroferrates with perchloric acid in acetic acid and are stable. The tetrachloroferrates react with benzenediazonium tetrafluoroborate to give 6,6aλ^4^‐diselena‐1,2‐diazapentalenes.
