Acetaldehyde reacts with methyl magnesium bromide followed by acid hydrolysis:
$\text{CH}_3\text{CHO} + \text{CH}_3\text{MgBr} \rightarrow \text{CH}_3\text{CH(OMgBr)CH}_3 \xrightarrow{\text{H}_2\text{O}/\text{H}^+} \text{CH}_3\text{CH(OH)CH}_3 + \text{Mg(OH)Br}$

Cumene (isopropylbenzene) is oxidized with air to cumene hydroperoxide, which on acid hydrolysis gives phenol and acetone:
$\text{C}_6\text{H}_5\text{CH(CH}_3)_2 \xrightarrow{\text{O}_2} \text{C}_6\text{H}_5\text{C(CH}_3)_2\text{OOH} \xrightarrow{\text{H}^+/\text{H}_2\text{O}} \text{C}_6\text{H}_5\text{OH} + \text{CH}_3\text{COCH}_3$
