Bis(thiophosphinic amidate) complexes (i.e., 1) of representative group 3 and lanthanide metals have been quantiatively prepared in situ from the corresponding thiophosphinic amides and Ln[N(TMS)2]3. These unusual pentacoordinate complexes exhibit very high activity as catalysts for intramolecular alkene hydroamination.
由相应的硫代次膦酰胺和 Ln[N(TMS)2]3 原位定量制备了代表性第 3 族和镧系金属的双(硫代次膦酸酰胺)配合物(即 1)。这些不寻常的五配位配合物作为分子内烯烃加氢胺化的催化剂表现出非常高的活性。
