Sodium ethoxide may either deprotonate the α-position of an ester molecule, forming an enolate, or the ester molecule may undergo a nucleophilic substitution called transesterification. If the starting material is an ethyl ester, trans-esterification is irrelevant since the product is identical to the starting material.
Alkoxy groups Aryloxy groups. In chemistry, the alkoxy group is an alkyl group which is singularly bonded to oxygen; thus R−O.Denoted usually with apostrophe('). The range of alkoxy groups is vast, the simplest being methoxy (CH 3 O−). [1]

Sodium methoxide is the simplest sodium alkoxide. With the formula CH 3 ONa , it is a white solid, which is formed by the deprotonation of methanol . It is a widely used reagent in industry and the laboratory.
Ether synthesis by reaction of salicylaldehyde with chloroacetic acid and sodium hydroxide [1] The Williamson ether synthesis is an organic reaction , forming an ether from an organohalide and a deprotonated alcohol ( alkoxide ).
When a small, unhindered base – such as sodium hydroxide, sodium methoxide, or sodium ethoxide – is used for an E2 elimination, the Zaytsev product is typically favored over the least substituted alkene, known as the Hofmann product. For example, treating 2-Bromo-2-methyl butane with sodium ethoxide in ethanol produces the Zaytsev product ...
Sodium methoxide, also called sodium methylate and sodium methanolate, is a white powder when pure. [6] It is used as an initiator of an anionic addition polymerization with ethylene oxide , forming a polyether with high molecular weight.
Common reaction conditions include use of sodium or potassium alkoxide as base in hexane or tetrahydrofuran solvents, at temperatures ranging between 200–400 °C. A hydrolysis step is also required in the synthesis. The Madelung synthesis is important because it is one of few known reactions that produce indoles from a base-catalyzed thermal ...
