We report a gold-catalyzed benzannulation of 3-hydroxy-1,5-enynes to generate tetrahydronaphthalenes. This mild process proves to be an effective method to synthesize various metasubstituted aromatic rings in good yields. [reaction: see text]

The synthesis and acid-catalyzed rearrangements of cross-conjugated cyclobutylidene ketone 1 are described. With strong Bronsted acids it gave a mixture of 5,7-dimethyltetralin 10 and 2-cyclohexenyl-1-methyl-3-phenylbenzene 11, the former by an initial retroaldol reaction and the latter by a series of tautomerizations and electrocyclic reactions following cation induced four-membered ring cleavage

In order to perform the analysis of the components contained in fossil fuels, carbon assignments of new methylated derivatives of tetralin and indan were obtained. Their chemical shifts were calculated by applying additivity rules.

Addition of lithium bis(methylenecyclopropyl) cuprate to α,β-unsaturated ketones provides an efficient route to methylenecyclopropylketones which on treatment with TiCl4 give a range of cyclised products.

The addition of tetrafluorobenzyne to benzene and mono-, di-, tri-, tetra-, and hexa-alkyl benzenes is described together with the additions to tetralins, naphthalenes and anthracene. In all these reactions only 1,4-addition products are isolated. The pyrolyses of some of the compounds isolated are reported. The proton magnetic resonance spectra of the products and the mass spectra of certain compounds
