A redox couple is a combination of a transition metal with an ion from another transition metal. These couples serve as electron donors in addition of halogenated carbohydrates to compounds with electron-deficient double bonds. There is some uncertainty as to whether a free radical or an organometallic compound is the intermediate in this type of reaction. Stereochemical evidence supports the radical pathway, but solvent effects indicate a more complicated situation.
