Activation of aryl halides at gold(i): Practical synthesis of (P,C) cyclometalated gold(III) complexes
Résumé
Taking advantage of phosphine chelation, direct evidence for oxidative addition of Csp2-X bonds (X = I, Br) to a single gold atom is reported. NMR studies and DFT calculations provide insight into this unprecedented transformation, which gives straightforward access to stable (P,C) cyclometalated gold(III) complexes. © 2014 American Chemical Society.
