Reductive transformations of gem-bromonitro compounds and α-nitro ketones were carried out conveniently with sodium dithionite by using dioctyl viologen as an electron-transfer catalyst in dichloromethane-water two-phase system: the bromine atom in gem-bromonitro compounds and the nitro group in α-nitro ketones are replaced by hydrogen.
