由于缺乏能够在Au(I)中心进行氧化加成反应的金催化剂,阻碍了金催化的芳基卤化物交叉偶联反应的发展。在本论文中,我们报道了新型三配位Au(I)催化剂的发展,它以N,N-双齿配体为载体,以膦或砷配体为连接体,在没有外部氧化剂的情况下进行C-H官能化,形成无均相偶联的联芳基。Au(I)催化剂的非对称性是促成这一必要的正交变换的关键。这项研究揭示了Au(I)催化联芳基合成的另一种潜力
The development of oxidant-free gold-catalyzed cross coupling reactions involving aryl halides have been hamstrung by the lack of gold catalysts capable of performing oxidative addition at Au(I) centers. Herein, we report the development of novel tricoordinate Au(I) catalysts supported by N,N-bidentate ligands and ligated by phosphine or arsine ligands for C-H functionalization without external oxidants to form biaryls with no homocoupling. The unsymmetrical character of the Au(I) catalyst is critical to facilitating this necessary orthogonal transformation. This study unveils yet another potential of Au(I) catalysis in biaryl synthesis
