我们合成了过渡金属 eta[sup +2]-SiH-[sub 4] 配合物的第一个例子，并获得了 eta][sup +2]-SiH[sub 4] 配合物和氢化硅烷基物质之间前所未有的互变异构平衡的光谱证据。 SiH[sub 4]的eta[sup+2]-配位随后Si-H键断裂产生氢化甲硅烷基物质，作为甲烷配位和随后活化的模型。 16 条参考文献、3 张图、1 个标签。
We have synthesized the first examples of transition metal [eta][sup +2]-SiH-[sub 4] complexes and obtained spectroscopic evidence for an unprecedented tautomeric equilibrium between an [eta][sup +2]-SiH[sub 4] complex and a hydridosilyl species. The [eta][sup +2]-coordination of SiH[sub 4] followed by Si-H bond cleavage to give the hydridosilyl species serves as a model for methane coordination and subsequent activation. 16 refs., 3 figs., 1 tab.
