Sodium ethoxide is commonly used as a base in the Claisen condensation [7] and malonic ester synthesis. [8] 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 ...

Several metal hydroperoxide complexes have been characterized by X-ray crystallography. Some form by the reaction of metal hydrides with oxygen gas: [17] L n M−H + O 2 → L n M−O−O−H (L n refers to other ligands bound to the metal) Some transition metal dioxygen complexes abstract H atoms (and sometimes protons) to give hydroperoxides:
For example, treating 2-Bromo-2-methyl butane with sodium ethoxide in ethanol produces the Zaytsev product with moderate selectivity. [9] Due to steric interactions, a bulky base – such as potassium tert-butoxide, triethylamine, or 2,6-lutidine – cannot readily abstract the proton that would lead to the Zaytsev product. In these situations ...
It may also be prepared from the reaction of sodium ethoxide, formed in-situ from sodium and absolute ethanol, and chloroform: [2] CHCl 3 + 3 Na + 3 EtOH → HC(OEt) 3 + 3 ⁄ 2 H 2 + 3 NaCl. Triethyl orthoformate is used in the Bodroux-Chichibabin aldehyde synthesis, for example: [3] RMgBr + HC(OC 2 H 5) 3 → RC(H)(OC 2 H 5) 2 + MgBr(OC 2 H 5)
In this case, diethyl diethylmalonate plus urea forms barbital under the action of sodium ethoxide. References This page was last edited on 1 May 2024, at 18:59 (UTC
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]
Diethylsulfoxylate can be made by reacting diethoxydisulfide with sodium ethoxide. [15] Sulfoxylic acid dimethyl ester (also called dimethylsulfoxylate or dimethoxysulfane) (S(OCH 3) 2) has been studied using electron diffraction, X-ray crystallography, Raman spectroscopy, and infrared spectroscopy. Studying this molecule is much easier than ...
