Participants
| Role | Name | HCID | Charge |
|---|---|---|---|
| Reactant | Sulfuric Acid | HCID 1118 | — |
| Reactant | Acetic Anhydride | HCID 7918 | — |
| Reactant | 4-(4-Acetylphenyl)phenol | HCID 10330806 | — |
| Product | 4-Acetoxy-4'-acetylbiphenyl | HCID 13531045 | 97% |
Reaction Steps
10.5 g of 4-hydroxy-4'-acetylbiphenyl (C) obtained in Example 1 was heated together with 20 ml of acetic anhydride in the presence of a small amount of concentrated sulfuric acid. Crude crystals thus obtained were recrystallized from carbon tetrachloride to obtain 12.5 g of 4-acetoxy-4'-acetylbiphenyl (1): ##STR51##
