Platinum complexes have been often considered as the least reactive of the group 10 triad metals. Slow kinetics are behind this lack of reactivity but, still, some industrially relevant catalytic process are dominated by platinum compounds and sometimes different selectivities can be found in comparison to Ni or Pd. Nevertheless, during the last years, it has been reported that the catalytic behaviour of well-defined platinum derivatives can be improved through a judicious choice of their electronic and steric properties, leading to highly electrophilic or low-electron count platinum systems. In this feature article, we highlight some catalytic processes in which well-defined electrophilic platinum complexes or coordinatively unsaturated systems play an important role in their catalytic activity.
铂配合物通常被认为是第10族三联金属中反应活性最低的。反应活性不足背后是动力学缓慢，但尽管如此，一些与工业相关的催化过程仍以铂化合物为主导，并且与镍或钯相比，有时会发现不同的选择性。然而，在过去几年中，有报道称，通过明智地选择其电子和空间性质，可以改善明确的铂衍生物的催化行为，从而产生高亲电性或低电子数的铂体系。在这篇专题文章中，我们重点介绍了一些催化过程，其中明确的亲电性铂配合物或配位不饱和体系在其催化活性中发挥着重要作用。
