Question
Explain reactions of haloarenes with sodium metal.
Solution
Haloarenes undergo Wurtz-Fittig reaction and Fittig reaction on reaction with sodium metal.
- The reaction of aryl halide with alkyl halide and sodium metal in dry ether to give substituted aromatic compounds is known as Wurtz-Fittig reaction.
e.g.
- If only aryl halide takes part in the reaction, the product is biphenyl (or diphenyl) and the reaction is known as Fittig reaction.
