Participants
| Role | Name | HCID | Charge |
|---|---|---|---|
| Reactant | Sulfuric Acid | HCID 1118 | — |
| Reactant | 4-(3,4-Diethylphenyl)butanoic acid | HCID 12366398 | — |
| Product | 6,7-Diethyl-3,4-dihydronaphthalen-1(2H)-one | HCID 12366399 | — |
Reaction Steps
Alternatively 4-(3',4'-diethylphenyl) butanoic acid (23.3 g; 0.106 mole) may be cyclised by stirring at 100° C. with 80% sulphuric acid (115 ml) for 11/2 hours. After dilution, extraction into ether, and distillation 15.83 g (74%) of the tetralone was obtained.
