Show how you would use the Friedel–Crafts acylation, Clemmensen reduction, and>or Gatterman–Koch synthesis to prepare the following compounds: (b)

Verified step by step guidance

1. Identify the target compound as tert-butyl phenyl ketone, which can be synthesized using Friedel-Crafts acylation.
2. Select the appropriate acyl chloride for the Friedel-Crafts acylation. In this case, use pivaloyl chloride (tert-butylcarbonyl chloride) as the acylating agent.
3. Use anhydrous aluminum chloride (AlCl_3) as the Lewis acid catalyst to facilitate the acylation reaction.
4. React benzene with pivaloyl chloride in the presence of AlCl_3 to form tert-butyl phenyl ketone.
5. Ensure the reaction conditions are anhydrous to prevent the deactivation of the AlCl_3 catalyst.
