The basicity of sodium ethoxide is such that it cannot fully deprotonate either of the ketones, but can produce small amounts of the sodium enolate of both ketones.
22.
When 2-bromo-2-methylbutane is treated with potassium " t "-butoxide instead of sodium ethoxide, the Hofmann product is favored.
23.
Sodium ethoxide may either deprotonate the ?-position of an ester molecule, forming an enolate, or the ester molecule may undergo a nucleophilic substitution called transesterification.
24.
The article on "'niobium ( V ) ethoxide "'was started by, likely by " borrowing " the ethanol article then blanking it.
25.
Gram-quantities were produced by the reduction of ethanol by sodium metal, followed by pyrolysis of the ethoxide product and washing with water to remove sodium salts.
26.
Basic conditions also increase the concentration of ethoxide ions, favouring the reaction as they are markedly more powerful nucleophiles for the substitution of chloride ligands than is the parent alcohol.
27.
In comparison, when sodium ethoxide is used, any nucleophilic attack at the carboxylate by the ethoxide will not give any side product; other alkoxide salts will cause scrambling by transesterification.

29.
Pyrolysis also produces a tantalum ( V ) oxide film by chemical vapor deposition in which case the tantalum ( V ) ethoxide is completely oxidised, producing carbon dioxide and water vapor:
30.
For this reason, the conjugate sodium alkoxide base of the alcohol formed ( e . g . sodium ethoxide if ethanol is formed ) is often used, since the alkoxide is regenerated.
