Friedel crafts acylation followed by clemmensen reduction forms n -propyl benzene as follows:
Friedel craft alkylation method can also be used for conversion of benzene to n -propyl benzene. But the electrophile CH3​−CH2​−C∥O⊕​ formed in F. C acylation method is more electrophilic in nature than the electrophile CH3​(CH2​C⊕H2​) formed in F. C alkylation method. Hence, F.C acylation followed by clemmensen reduction is more preferrable.
