Directed metalation is well-known as the most valuable methodologies for the regio- and stereoselective iteration of organometallic species, the iteration of which unavoidably results in the selective formation of natural items. Cyclometalation utilizing Li, Mn, and Pd, and directed hydrometalation and carbometalation utilizing Al and Zn, were applied for regio- and/or stereoselective synthesis for many years.

1 By Oxidation Reactions (J-1) There are other methods of synthesis of metal alkoxides. During the synthesis of uranium tetraethoxide, Gilman and co-workers379,380 observed that it could be oxidized by an oxidizing agent such as dry air to uranium pentaethoxide. The exact mechanism is not known but it is assumed that uranium(IV) is oxidized to uranium (V); the yield of product was only 65%: 5U(OEt)4 C O2 ! 117 Alternatively when uranium tetraethoxide was treated with bromine in 2:1 molar ratio followed by the addition of 2 moles of sodium ethoxide, uranium pentaethoxide was obtained in 90–95% yield:378,379 2U(OEt)4 C Br2 2U(OEt)4 Br C 2NaOEt !
4. 5. 6. 7. 7). 1, the observed molecular complexities in nonpolar solvents and the volatility of alkoxides of metals in general appear to be governed by the nature and size of the metal atoms and the inductive effect coupled with the steric demand of the alkoxide groups. 14.
Reactions of M(NR2 )4 (M D V, Nb, R D Et; Cr, R D Et or Pri ; and Mo, R D Me) with 1-adamantyl alcohol have been investigated by Wilkinson and co-workers169 and isolated mononuclear alkoxides of these metals in the tetravalent state. The reaction represented by Eq. 101) is, however, sometimes accompanied by a change in the oxidation state of the metal. For example, Cr(NEt2 )4 reacts with primary and secondary alcohols335 according to Eq. 107). Only tertiary alcohols and the sterically demanding 3,3-dimethyl-2-butanol,336 which are not prone to this type of oxidation, are known331 to give chromium(IV) alkoxides.
