Question

The reaction $C_6{H}_{5}I+2Na+C{H}_{3}I\to C_6{H}_{5}C{H}_3+2NaI$ is called:

• A. Wurtz reaction
• B. Fittig reaction
• C. Wurtz - Fittig reaction
• D. Sandmeyer reaction

Answer 1

Answer: (C)

Wurtz - Fittig reaction

Fittig reaction: Aryl chloride reacts with $Na$ in presence of dry ether and diaryl forms as product.
Reaction:
$2C_6{H}_{5}Cl+2Na\to C_6{H}_5-C_6{H}_5+2NaX$

Wurtz reaction:
$R-X+2Na+R-X\to R-R+2NaX$

Wurtz-fittig reaction:
$R-X+2Na+Ph-X\to Ph-R+2NaX$
