anions, in which one of the PF6− anions occupies the centre of the Cu8 cube without any interaction. The copper(I) cubic cages are found to be highly active catalysts in clickchemistry as well as hydroamination reactions. The scope of the catalytic reactions has been investigated with thirty-five different combinations of click reactions and six different combinations of the hydroamination of alkynes

ligands-supported copper(I) complexes for C–N and C–Si bond formation reactions are described. The syntheses and characterization of eight mononuclear copper(I) chalcogenone complexes, two polynuclear copper(I) chalcogenone complexes and one tetranuclear copper(I) phosphine complex are reported. All these new complexes were characterized by CHN analysis, FT-IR, UV-vis, multinuclear NMR and single crystal X-ray
描述了 C、S、Se 和 P 供体配体负载的铜 ( I ) 配合物用于 C-N 和 C-Si 键形成反应的首次比较研究。报道了8个单核铜( I )硫族酮配合物、2个多核铜( I )硫族酮配合物和1个四核铜( I )膦配合物的合成和表征。通过 CHN 分析、FT-IR、UV-vis、多核 NMR 和单晶 X 射线衍射技术对所有这些新配合物进行了表征。这些配合物的单晶 X 射线结构描绘了铜存在广泛的配位环境(I) 中央。这是金属-膦、金属-NHC和金属-咪唑啉-2-硫属元素酮在C-N和C-Si键形成反应中的首次比较研究。在所有催化剂中,单核铜( I )硫酮、单核铜( I )N-杂环卡宾和四核铜( I )膦对1,2,3-三唑的合成和交叉脱氢反应非常活跃炔烃与硅烷的偶联。末端炔烃与硅烷的交叉脱氢偶联代表了由金属-咪唑啉-2-硫属元素酮介导的催化过程的首次报道。
