Enyne [3]cumlenals have been shown to undergo a Bergman cyclization or an intramolecular [2+2] cycloaddition depending on the nature of substituents on the yne carbon. A hydrogen substituted [3]cumulenal is cleanly converted to a naphthalene product while a trimethylsilyl substituted substrate produces a cyclobutene product.
