Hexaphenyl-1,2-Diphosphonium Dication [Ph3P–PPh3]2+: Superacid, Superoxidant, or Super Reagent?
The oxidation of triphenylphosphine by perfluorinated phenaziniumF aluminate in difluorobenzene affords hexaaryl-1,2-diphosphonium dialuminate 1. Dication 12+ is valence isoelectronic with elusive hexaphenylethane, Hexaphenyl-1,2-Diphosphonium Dication [Ph3P–PPh3]2+: Superacid, Superoxidant, or Super Reagent?
