本文报道了利用膦螯合作用，在金原子上氧化加成C-sp（2）-X键（X = I，Br）的直接证据。NMR研究和DFT计算提供了对这一前所未有的转变的深入了解，这使得直接获得稳定的（P，C）环化金（III）配合物。
Taking advantage of phosphine chelation, direct evidence for oxidative addition of C-sp(2)-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.
