The structure of the methoxide ion. In chemistry, an alkoxide is the conjugate base of an alcohol and therefore consists of an organic group bonded to a negatively charged oxygen atom. They are written as RO−, where R is the organyl substituent. Alkoxides are strong bases [citation needed] and, when R is not bulky, good nucleophiles and good ...
Sodium methoxide is a routinely used base in organic chemistry, applicable to the synthesis of numerous compounds ranging from pharmaceuticals to agrichemicals. [ 4 ] As a base, it is employed in dehydrohalogenations and various condensations. [ 5 ] It is also a nucleophile for the production of methyl ethers. [ 6 ]
The Williamson ether synthesis is an organic reaction, forming an ether from an organohalide and a deprotonated alcohol (alkoxide). This reaction was developed by Alexander Williamson in 1850. [2] Typically it involves the reaction of an alkoxide ion with a primary alkyl halide via an S N 2 reaction. This reaction is important in the history of ...
Sodium ethoxide, also referred to as sodium ethanolate, is the ionic, organic compound with the formula CH3CH2ONa, C 2 H 5 O Na, or NaOEt (Et = ethyl). It is a white solid, although impure samples appear yellow or brown. It dissolves in polar solvents such as ethanol. It is commonly used as a strong base. [2]
The alkoxide ion is a strong base so the proton is transferred from the carboxylic acid to the alkoxide ion, creating an alcohol: saponification part III. In a classic laboratory procedure, the triglyceride trimyristin is obtained by extracting it from nutmeg with diethyl ether. Saponification to the soap sodium myristate takes place using NaOH ...
An alkoxide can refer to salts of alcohols, and they are ionic compounds containing an alkoxide ions RO −; it is a derivative of an alcohol where the hydrogen of the –OH group is replaced by a metal, [2] for example sodium salt of ethanol (CH 3 CH 2 OH) is sodium ethoxide, containing ethoxide anions CH 3 CH 2 O − and sodium cations Na +.
Cannizzaro reaction. The Cannizzaro reaction, named after its discoverer Stanislao Cannizzaro, is a chemical reaction which involves the base -induced disproportionation of two molecules of a non- enolizable aldehyde to give a primary alcohol and a carboxylic acid. [ 1 ][ 2 ] Cannizzaro first accomplished this transformation in 1853, when he ...
claisen-condensation. RSC ontology ID. RXNO:0000043. The Claisen condensation is a carbon–carbon bond forming reaction that occurs between two esters or one ester and another carbonyl compound in the presence of a strong base. The reaction produces a β-keto ester or a β- diketone. [1] It is named after Rainer Ludwig Claisen, who first ...
