Reaction de wurtz
In organic chemistry, the Wurtz reaction, named after Charles Adolphe Wurtz, is a coupling reaction whereby two alkyl halides are treated with sodium metal to form a higher alkane. 2 R−X + 2 Na → R−R + 2 NaX The reaction is of little value except for intramolecular versions. A related reaction, which combines alkyl … See more The reaction proceeds by an initial metal–halogen exchange, which is described with the following idealized stoichiometry: R−X + 2 M → RM + MX This step may … See more Although the Wurtz reaction is only of limited value in organic synthesis, analogous couplings are useful for coupling main group … See more The reaction is intolerant of a range of functional groups which would be attacked by sodium. For similar reasons, the reaction is conducted in unreactive solvents such as ethers. In efforts to improve the reaction yields, other metals have also been … See more • Wurtz–Fittig reaction • Ullmann reaction See more • Adolphe Wurtz (1855).
