| 摘 要： | A variety of gold（Ⅲ） adducts having a-ligated oxygen-donor ligands have been prepared from [Au（ppy）Cl2]（ppy.phenylpyridine）（1） either by partial or total replacement of the chloride ions. The new species comprise hydroxo-[Au（ppy）（OH）Cl]（2）, and [Au（ppy）（OH）2]（3）, oxo-[Au2（ppy）2（μ-O）2]（4）, acetate-[Au（ppy）（O2CMe2）] （5）, and alkoxo complexes-[Au（ppy）（OR）Cl]（6, 7） and [Au（ppy）（OR）2]（8--10）（R=Me, 6 and 8; Et, 7 and 9; Pr, 10）. The dihydroxo and the oxo complexes can be interconverted by refluxing the former in anhydrous THF and the latter in water. The hydroxides 2 and 3 and the acetato complex 5 undergo σ-ligand metathesis in ROH solution（R=Me, Et or Pr） to give the corresponding alkoxides.

| Abstract: | A variety of gold(III) adducts having σ-ligated oxygen-donor ligands have been prepared from [Au(ppy)Cl2](ppy·phenylpyridine)(1) either by partial or total replacement of the chloride ions. The new species comprise hydroxo-[Au(ppy)(OH)Cl](2), and [Au(ppy)(OH)2](3), oxo-[Au2(ppy)2(μ-O)2](4), acetate-[Au(ppy(O2CMe2)] (5), and alkoxo complexes-[Au(ppy)(OR)Cl](6, 7) and [Au(ppy)(OR)2](8-10)(R=Me, 6 and 8; Et, 7 and 9; Pri,10). The dihydroxo and the oxo complexes can be interconverted by refluxing the former in anhydrous THF and the latter in water. The hydroxides 2 and 3 and the acetato complex 5 undergo σ-ligand metathesis in ROH solution(R=Me, Et or Pri) to give the corresponding alkoxides. |
