Từ Hexan

$\text{CH}_3\text{-(CH}_2)_4\text{-CH}_3 \xrightarrow[\text{nhiệt độ cao}]{\text{Pt/Al}_2\text{O}_3} \text{C}_6\text{H}_6 + 4\text{H}_2$

Từ heptan:

$\text{CH}_3\text{-(CH}_2)_5\text{-CH}_3 \xrightarrow[\text{nhiệt độ cao}]{\text{Pt/Al}_2\text{O}_3} \text{C}_6\text{H}_5\text{CH}_3 + 4\text{H}_2$

Từ benzene , ethylene:

$\text{C}_6\text{H}_6 + \text{CH}_2=\text{CH}_2 \xrightarrow[\text{-H}_2]{\text{AlCl}_3, \text{ nhiệt độ cao}} \text{C}_6\text{H}_5\text{CH}=\text{CH}_2$
