    The previous four chapters describe electron-transfer reac­tions between carbohydrate deri­va­tives and transition-metal ions. Some ions [chromium(II), samarium(II), and titanium(III)] are elec­tron donors and others [cobalt(III), cerium(IV), manganese(III), and mercury(II)] are electron acceptors. Another form in which a transition-metal ion can partic­ipate in a radical reaction is as a part of a redox couple. (A redox couple is a combin­ation of a transition metal and an ion from a different trans­ition metal that act together in donating electrons to organic compounds.) Redox couples pro­mote the addition of halo­genated carbo­hy­drates to electron-deficient double bonds, and they par­tic­ipate in the conver­sion of glycosyl halides into glycals and simple reduc­tion products.
