Facile Formation of Seven- and Eight-Membered Cycloalkenes via Catalytic and Cyclic Carbopalladation of Allenes

Article abstract of DOI:10.1021/jo00096a011

Cyclization of allene-containing aryl and alkenyl halides under the influence of a catalytic amount of a Pd-phosphine complex, e.g., Cl2Pd(PPh3)2, proceeds via carbon-carbon bond formation at the central carbon atom of the allene moiety, providing a novel
