1-Tetralone is an organic chemical compound with the molecular formula C₁₀H₁₀O. It is a common intermediate in organic synthesis. It is a ketone derivative of tetralin, a hydrogenated derivative of naphthalene. A related compound is 2-tetralone.

Preparation

1-Tetralone can be prepared by several methods. A typical methods involve intramolecular cyclisation of phenylbutyric acid.^[2]

The Haworth reaction is a classic method for the synthesis of tetralone.^[3][4] Benzene is reacted with succinic anhydride by a Friedel–Crafts acylation, the intermediate product is reduced and a second Friedel–Crafts acylation takes place upon the addition of acid.

Haworth reaction

Use

1-Tetralone is a precursor to 1-naphthol by dehydrogenation:^[5]

C₁₀H₁₀O → C₁₀H₇OH + H₂
