Uranium hexaethoxide

The highest oxidation state (+6) appears not to be the most stable one for the alkoxides. Uranium hexaethoxide is easily converted into pentaethoxide on action of different reducing agents such as ethylmercaptane, diethylamine, and soon. Its interaction with uranium tetraethoxide leads to coproportionation [856] ... 

It was also observed that uranium pentaethoxide was suceptible to oxidation by air or molecular oxygen to give uranium hexaethoxide, but the yield of the product was very poor. Gilman et al found that better yields were obtained by oxidizing the double ethoxide of sodium and uranium, NaU(OEt)6, in place of uranium pentaethoxide, U(OEt)5, with bromine, lead tetraacetate or benzoyl peroxide the yields in these reactions were 5-10, 20, or 40-60%, respectively ...
