title: Facile assembly of indeno[1,2-c]chromenes via a palladium-catalyzed reaction of 2-alkynylhalobenzene.
abstract: 2-Alkynylhalobenzene reacts with 2-alkynylphenol in the presence of a palladium catalyst, leading to indeno[1,2-c]chromenes in good to excellent yields. Furthermore, the scaffold of indeno[1,2-c]chromene could be constructed via a palladium-catalyzed reaction of 2-alkynylbromobenzene with water, in which four bonds are formed with high efficiency.
