Different Pt(IV), Pt(II) and Pt(0) catalysts were screened for the hydrosilylation of fatty acid esters containing terminal as well as internal double bonds. The reaction of terminally unsaturated fatty acid esters proceeded smoothly with short reaction times for nearly all examined catalysts, whereas Pt(IV) species and Pt(II) or Pt(0) species with labile ligands were sufficiently active in the reaction
筛选了不同的 Pt(IV)、Pt(II) 和 Pt(0) 催化剂用于含有末端和内部双键的脂肪酸酯的氢化硅烷化。对于几乎所有检查过的催化剂,末端不饱和脂肪酸酯的反应在较短的反应时间内顺利进行,而具有不稳定配体的 Pt(IV) 物种和 Pt(II) 或 Pt(0) 物种在内部不饱和化合物的反应中具有足够的活性. 对于亚油酸甲酯,在氢化硅烷化之前观察到两个内部双键的共轭。该反应在物质以及允许催化剂循环和再利用的溶剂系统中进行。然而,在这些系统中,发现氢化和双键异构化是副反应。
