Oxidative Radical Reactions by Other Metals

Finally, pentavalent vanadium complexes were employed as one-electron oxidants. The oxidative coupling of the electron-rich arene 48 in the presence of VOF3 was the key step in the total synthesis of stegnacin however, the cyclization to the 

In summary, oxidative radical reactions by other metals are less common than single-electron transfer to cerium(IV), iron(III), copper(II), and especially manganese(III) complexes. However, even for manganese(III) acetate and cerium(IV) ammonium nitrate the synthetic potential is not completely utilized. During the next few years, many new applications should arise, which will focus on stereoselective reactions and the synthesis of complex organic molecules.
