The Wurtz Coupling is one of the oldest organic reactions, and produces the simple dimer derived from two equivalents of alkyl halide. This type of reaction fails in case of tertiary halides. The Wurtz reaction is seldom used because of side reactions.

The Wurtz reaction, named after Charles Adolphe Wurtz, is a coupling reaction in organic chemistry, organometallic chemistry and recently inorganic main group polymers, whereby two alkyl halides are reacted with sodium metal in dry ether solution to form a higher alkane. Example: Methyl bromide on treating with sodium metal in dry ethereal solution gives ethane. For example, it is intolerant of a range of functional groups. In the case of (1,3), (1,4), (1,5), (1,6) dihalides, it leads to formation of cyclic products. Bicyclobutane was prepared this way from 1-bromo-3-chlorocyclobutane in 95% yield.

The reaction is conducted in refluxing dioxane, at which temperature, the sodium is liquid. • In this reaction alkyl halides are treated with sodium metal in dry ethereal (free from moisture) solution to produce higher alkanes and it is also used for the preparation of higher alkanes containing even number of carbon atoms. The Wurtz reaction, named after Charles Adolphe Wurtz, is a coupling reaction in organic chemistry, organometallic chemistry and recently inorganic main group polymers, whereby two alkyl halides are reacted with sodium metal in dry ether solution to form a higher alkane: . [3] It has limited use to the synthesis of symmetric alkanes. A reaction related to the Wurtz Reaction in which aryl halides are used instead of alkyl halides is often called the Wurtz-Fittig reaction and is a very important named reaction in organic chemistry. The alkyl radical then accepts an electron from another metal atom to form an alkyl anion. Due to several limitations this reaction is seldom used. For example, it is intolerant of a range of functional groups. Applications of Wurtz Fittig reactions are limited. This can be explained by the formation of free radical intermediate and its subsequent disproportionation to give alkene. Other metals have also been used to effect the Wurtz coupling, among them silver, zinc, iron, activated copper, indium and a mixture of manganese and copper chloride.

Wurtz coupling is, however, useful in closing small, especially three-membered, rings. Example of Wurtz Reaction.

Cloudflare Ray ID: 5f7c3e902c93fd52 Applications of Wurtz – Fittig Reaction Wurtz – Fittig reaction is useful in the laboratory for synthesis of organosilicon compounds. For example, t-butyltriethoxysilane can be prepared by Wurtz – Fittig reaction. Due to several limitations this reaction is seldom used. Limitation of Wurtz Reaction. If you are at an office or shared network, you can ask the network administrator to run a scan across the network looking for misconfigured or infected devices. Alkyl halide in presence of dry ether medium when treated with sodium metal yields di-alkane.
