Platinum(II) complex [Pt(I^tBu′)(I^tBu)][BAr^F₄] (1a) is a highly active and selective catalyst in the dehydrocoupling of amines and silanes at part-per-million catalyst loadings (up to 10 ppm, 0.001 mol%), achieving the highest TON and TOF numbers reported in the literature (up to 1 mmol scale). NMR studies suggest a process taking place through electrophilic activation of the silane by the platinum species, assisted by an amine.

以百万分之几的催化剂负载量选择性催化合成氨基硅烷

铂（II）络合物[Pt（I ^t Bu'）（I ^t Bu）] [BAr ^F ₄ ]（1a）是胺和硅烷在百万分之几的催化剂负载量下脱氢偶联的高活性和选择性催化剂（最高可达10 ppm，0.001 mol％），实现了文献中报道的最高TON和TOF值（最高1 mmol规模）。NMR研究表明，该过程是通过在胺的协助下铂类对硅烷的亲电活化而发生的。
