tetranuclear gold complexes, a structurally unprecedented octanuclear complex with a planar [Au(I) 8 ] core, and pentanuclear [Au(I) 4 M(I) ] (M=Cu, Ag) complexes is presented. The linear [Au(I) 4 ] complex undergoes C-H functionalization of carbonyl compounds under mild reaction conditions. In addition, [Au(I) 4 Ag(I) ] catalyzes the carbonylation of primary amines to form ureas under homogeneous conditions
提出了四核金配合物、结构上前所未有的具有平面 [Au(I) 8 ] 核心的八核配合物和五核 [Au(I) 4 M(I) ] (M=Cu, Ag) 配合物的合成。线性[Au(I) 4 ]络合物在温和的反应条件下经历羰基化合物的CH官能化。此外,[Au(I) 4 Ag(I) ]在均相条件下催化伯胺的羰基化形成脲,其效率高于金纳米颗粒所达到的效率。
