Negishi et al. [258] have initially suggested that the applicable metals for the alkynyl cross-couplings may be limited to Zn, Sn, B, and to a lesser extent Al. Nevertheless, the recent significant progress in ligands, catalysts, and reaction conditions has paved the way for efficient cross-coupling of several other alkynylmetals. [Pg.739]
