在本报告中,我们介绍了六种新型中性铂配合物的合成,使用容易获得的 P,N-供体配体,通过简单的两步程序合成。随后,我们研究了它们在末端烯烃加氢元素化中的催化活性,强调了它们在材料和天然产物化学中的多功能用途。在低催化剂负载量下,硅、锗和氢化硼仅以反马尔可夫尼科夫方式有效加成到 CC 键上。此外,我们的底物范围涵盖广泛的脂肪族和芳香族烯烃,其取代基具有不同的电子特性。与许多以前的 Pt 配合物相比,我们的催化系统对其他不饱和官能团(例如羰基和内部 CC 键)表现出卓越的化学选择性。值得注意的是,它还表现出对羟基、烷氧基、甲硅烷基和硫醚部分的显着耐受性。此外,我们还强调了催化剂的性能,展示了其在多个催化循环中保持一致的活性和选择性的能力。

neutral platinum complexes employing readily available P,N-donor ligands through a straightforward two-step procedure. Subsequently, we investigated their catalytic activity in the hydroelementation of terminal olefins, highlighting their versatile utility in material and natural product chemistry.
