顶级猫：[（NHC）Yb{N（SiMe（3））（2）}（2）]加合物（NHC = N-杂环卡宾）是硅烷与一系列伯胺和仲胺在温和反应条件下以高产率（82-100%）催化交叉偶联生成甲硅烷基胺的有效催化剂。稀土金属甲硅烷基酰胺的催化活性和选择性通过改变NHC的空间体积来调节。
Top cat: [(NHC)Yb{N(SiMe(3))(2)}(2)] adducts (NHC = N-heterocyclic carbene) are efficient catalysts for catalytic cross-dehydrogenative coupling of silanes with a range of primary and secondary amines to yield silylamines in high yields (82-100%) under mild reaction conditions. The catalytic activity and selectivity of the rare-earth-metal silylamides are modulated by altering the steric bulk of the NHC.
