Applications of WurtzFittig reactions are limited. It is named for the French chemist Alexandre Lon tard (5 January 1852, Alenon 1 May 1910). Two aryl halides react with sodium metal in the presence of dry ether to form a diphenyl. Students must learn the reactions along with the catalyst and end products. What is Finkelstein reaction Class 12? Wilhelm Rudolph Fitting and Charles Adolphe Wurtz. A process during which chemical bonds between atoms are broken and new ones are formed. According to this mechanism, sodium metal acts as a mediator and the formation of an alkyl radical and aryl radical takes place.
