The discovery of the remarkable biological activity of natural enediynes and enyne allenes has further fueled interest in understanding the fundamentals that govern these transformations. Indeed, cycloaromatization reactions have served as a productive playground for testing numerous concepts related to structure and reactivity of organic and organometaUic compounds [2].
