Tetralin (1,2,3,4-Tetrahydronaphthalene) is a hydrocarbon having the chemical formula C10H12. 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,[1] or simply through the hydrogenation of napthalene in the presence of a platinum catalyst.
