The synthesis of highly substituted indenes has been achieved by three different transition metal-mediated methods. The first method involves the palladium-catalyzed carboannulation of internalalkynes. The second method utilizes a two-step approach, which involves first the palladium/copper-catalyzed cross-coupling of terminalalkynes with appropriately functionalized aryl halides, followed by copper-catalyzed

A substoichiometric copper iodide catalysed synthesis of indene and dihydronaphthalenederivatives has been accomplished. This protocol is compatible with functional groups, and results in various scaffolds of indene and dihydronaphthalenederivatives in good to high yields. By employing this protocol, a functionalised cyclohexenone derivative is also achieved.
