A palladium(0)-catalyzed ring-opening cross-coupling reaction between tert -cyclobutenols and arylhalides produces γ-arylated β,γ-unsaturated ketones. In the case of arylhalides bearing functional groups at the ortho position, the resulting ring-opened ketones undergo intramolecular condensation to afford bicyclic aromatic compounds.

A new and highly convenient Au-catalyzed cyclization of alkyne-propargylic acetates leading to 2-acyl-3-arylnaphthalene derivatives is described; these are possible candidates for light-emitting materials.
