✦ Synopsis

Palladium-catalyzed cyclizadon of appropriately structured triynes, haloalkenyldiynes, or haloalkenylalkyne-alkyne mixtures can provide the corresponding benzene derivatives, while the Pd-catalyzed intermolecular reaction of diynes with alkenyl halides can give fulvene derivatives.

Cascade cat%opaIladation has been implicated in the [2+2+2] cyclotrlmerization of alkynes to product benzene derivatives'. The intermolecular version of the reaction, however, does not provide a generally satisfactory route to benzene derivatives with good control of "pair" selectivity and regioselectivity. We recently reported a highly regiocontrolled and partially intramolecular reaction to give a benzene derivative via carbopalladation2.3
