The reaction of the diselenide dication salt, 1,5-diselenoniabicyclo<3.3.0>octane bis(hexafluorophosphate) (1) with 1,5-diselenacyclooctane (2) gave the corresponding cation radical by single-electron transfer.The dication salt 1 was reduced upon treatment with fluorenyl-lithium, Na2S, NaBH4; it did not deprotonate.The cyclic voltammetry of 1 shows the reversible reduction peak at remarkably low reduction potential.
