Palladium-Catalyzed Bisolefination of C−C Triple Bonds: A Facile Method for the Synthesis of Naphthalene Derivatives

A highly efficient and mild palladium-mediated bisolefination of C−C triple bonds is described for the first time. With different types of olefin employed, this reaction terminates in diverse fashions. In addition to the merit of using oxygen as the sole oxidant, this reaction exhibits high reactivities and functionality tolerance simultaneously, thus providing a promising method for the synthesis of naphthalene derivatives.
