A reaction to prepare alkanes by reacting a haloalkane with sodium:2RX+2Na → 2NaX+RR The haloalkane is refluxed with sodium in dry ether. The method is named after the French chemist Charles-Adolphe Wurtz (1817–84). The analogous reaction using a haloalkane and a haloarene, for example:C6H5Cl+CH3Cl+2Na → 2NaCl+C6H5CH3 is called the Fittig reaction after the German chemist Rudolph Fittig (1835–1910).
2RX+2Na → 2NaX+RR
C6H5Cl+CH3Cl+2Na → 2NaCl+C6H5CH3
