This NSF Young Investigator award in the Inorganic, Bioinorganic, and Organometallic Chemistry Program supports research on metal silicides by Dr. Ziling B. Xue of the Chemistry Department, University of Tennessee at Knoxville. Two areas are emphasized: development of synthetic routes to metal silicides and polysilanes, and investigation of the mechanism of solid state organometallic reactions. On the first topic, early transition metal silyl complexes which do not contain cyclopentadiene or analogous ligands will be prepared; very few compounds of this type are known. These compounds will be used to develop a new route to metal silicides and polysilanes, which are useful for electronic devices. Tetrahydrosilane will also be used to form metal silicides under chemical vapor deposition conditions. In the second area, solid-gas reactions of alkyl compounds with phosphines will be studied. Research will focus on the factors affecting retention of solid state structure during reaction. Instrumentation from Oak Ridge National Laboratory will be used for some of the structural determinations. This work has implications for synthesis of heterogeneous catalysts.

这项NSF年轻研究者奖在田纳西州诺克斯维尔大学化学系的Ziling B. Xue博士B. Ziling B. 强调了两个领域：发展到金属硅和多硅烷的合成途径，以及研究固态有机金属反应机理。 在第一个主题上，将制备不包含环戊烯或类似配体的早期过渡金属配合物；很少有这种类型的化合物已知。 这些化合物将用于开发新的硅胶和多硅烷途径，这些途径可用于电子设备。 四氢烷烷也将用于在化学蒸气沉积条件下形成金属硅硅。 在第二个区域，将研究烷基化合物与磷的固体气体反应。 研究将集中于影响反应过程中固态结构的保留的因素。 橡树岭国家实验室的仪器将用于某些结构测定。 这项工作对合成异质催化剂具有影响。
