title: Synthesis of Benzofulvene Derivatives from Diarylacetylenes via Pd(II)-Catalyzed Alkyne-Directed C(sp(2))-H Bond Activation.
abstract: A novel and efficient protocol for the synthesis of benzofulvene derivatives from easily available diarylacetylenes has been developed. The reaction proceeds through rarely reported carboxylate-assisted alkyne-directed ortho-C(sp(2))-H palladation followed by insertion of another diarylacetylene.
