WebThis reduction of the C = O group next to an aromatic ring is an important synthetic tool. Recall the Friedel-Crafts alkylation from Section 16.3. When attaching larger alkyl groups to arenes there is a possibility of rearrangement of the alkyl group structure. To generate the target compound (in this case n ‑propylbenzene) in a more ...
