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 ... WebJan 1, 1984 · After an additional 24 h of stirring, a 62% yield of 1,4-dimethylcyclohexene was obtained. 15. We have ascertained that when n-butylamine is used alone, no reduction occurs. Thus, when 0.025 mol of p-xylene was stirred with 0.125 g at of calcium in 75 mL of n-butyl- amine for 4 days, 88% of the p-xylene was recovered unchanged. 16.
