Soluble Dithionite Salts

1. Tet. Lett., 1977: Title: ORANGE BENZENE. NEUTRAL DICHROMATE OXIDATIONS IN ORGANIC SOLVENTS [not on dithionite but use of cation exchage agents to make insoluble dianion soluble in non-aqueous solutions] LINK

2. Bioinorg. Chem. 1978: Title: CROWN ETHER COMPLEXES OF SODIUM DITIONITE AND THEIR USES AS REDUCING AGENTS [products are poorly characterized but earliest indication that salts with larger cations are soluble] LINK


3. J. Chem. Soc., Chem. Commun., 1979: Title: Stereochemistry of Methylcyclohexanones Reduction by Sodium Dithionite under Conventional and Phase Transfer Conditions [product not isolated or characterized] LINK

4. Inorg. Chem., 1987, : Title: Synthesis of Tetraethylammonium Dithionite and Its Dissociation to the Sulfur Dioxide Radical Anion in Organic Solvents [Cation exchange using column chromatography, isolated and characterized, equilibriums determined] LINK


5. Inorg. Chem., 1991: Title: Spectroscopic Evidence for a Centrosymmetric Dithionite Anion in the Solid State:Vibrational Spectroscopy of Tetraethylammonium Dithionite [Spectroscopic study on sample provided by previous authors to determine structure of anion] LINK 6. Reactive Polymers, 1991: Title: REDUCTIONS WITH POLYMER SUPPORTED DITHIONITE ANIONS - REGIOSELECTIVITY IN CONJUGATED SYSTEMS [not exactly a soluble dithionite but ion exchange involving dithionite] LINK

7. J. Chem. Soc., Chem. Commun., 1992: Title: A New Electron Mediator: Reduction by Na2S204 in Organic Media of a Novel Viologen Functionalized with Crown Ether Structure [pretty clever work, authors wanted efficient reduction with dithionite so they attached crown ethers to their starting material, seems to have worked, ominous comment on the reductions working better when add small amout of water to non-aqueous solvents though] LINK
