'''Tetralin''' (1,2,3,4-Tetrahydronaphthalene) is a [[hydrocarbon]] having the chemical formula C<sub>10</sub>H<sub>12</sub>. This molecule is similar to the [[naphthalene]] molecular structure but where 2 of the double bonds are saturated. Its CAS number is 119-64-2.

The compound can be synthesized in a [[Bergman cyclization]]. In a classic [[named reaction]] called the '''Darzens tetralin synthesis''' ([[Auguste George Darzens]] (1867-1954), 1926) derivatives can be prepared by intramolecular ring-closing reaction of an 1-aryl-4-pentene with concentrated [[sulfuric acid]],<ref>http://www.chempensoftware.com/reactions/RXN053.htm</ref> or simply through the hydrogenation of napthalene in the presence of a platinum catalyst.
