The synthesis of 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 with efficiencies higher than those achieved by gold nanoparticles.
本文报道了四核金配合物、具有平面[Au(I)8]核心的结构前所未有八核配合物以及五核[Au(I)4M(I)]（M=Cu，Ag）配合物的合成。线性[Au(I)4]配合物在温和的反应条件下可实现羰基化合物的 C-H 官能团化。此外，[Au(I)4Ag(I)]在均相条件下可催化伯胺的羰基化反应生成脲，其效率高于金纳米颗粒。
