Reaction de wurtz

WebWurtz reaction is a chemical coupling reaction used to synthesize alkanes. The reaction takes place in an anhydrous environment. Wurtz reaction uses free radicals as an intermediate to induce nucleophilic substitution. Asymmetric haloalkanes are not used in the reaction because they produce mixtures of alkanes that are hard to separate. WebSep 15, 2010 · This reaction is a sodium-mediated coupling of two alkyl halides into a higher order of hydrocarbon and is generally known as the Wurtz synthesis. Analogously, the coupling between an alkyl halide and a Grignard reagent is referred to as the Grignard–Wurtz coupling. It has been reported that the Wurtz synthesis might not proceed through a ...

WebWurtz-Fittig Reaction. This reaction allows the alkylation of aryl halides. The more reactive alkyl halide forms an organosodium first, and this reacts as a nucleophile with an aryl halide as the electrophile. Excess alkyl halide and sodium may be used if the symmetric coupled alkanes formed as a side product may be separated readily.
