Quinolines may be synthesized by Pd-catalyzed reaction with allyl alcohols: Tetrahedron Lett., 32, 569 (1991). Reacts with unsymmetrical acetylenes in the presence of Palladium(II)- acetate, to give indoles substituted at the 2- and/or 3-positions: J. Am. Chem. Soc., 113, 6689 (1991). Under similar conditions, ketones with an ɑ-methylene group also give indole derivatives: J. Org. Chem., 62, 2676 (1997).
