| Popis: | The synthetic routes to vanadium(II) complexes from metallic vanadium and from compounds in higher oxidation states, comprising both chemical and electrochemical methods, are reviewed. The reduction of vanadium(III) chloride by Zn seems to be the simplest entry to useful starting materials such as trichlorohexakis(tetrahydrofuran)divanadium(1+), dichlorobis(tetramethylethylenediamine)vanadium and diiodotetrakis(tetrahydrofuran)vanadium. The chemistry is not dominated by a single ligand type, and O-, N- and P-donors are all used. Few dinitrogen complexes of vanadium-(II) and -(III) have been reported and all contain bridging dinitrogen. The protonation of these compounds yields ammonia only from vanadium(II); the higher oxidation state regenerates dinitrogen. The extensive chemistry of trinuclear vanadium(II) complexes now being revealed may also be relevant to vanadium(II)-catechol-methoxide nitrogen-fixing systems. |
