Synthetic, Structural and Mechanistic Studies of Monomeric Alkyl, Hydride, Silyl, Oxo and Nitrido Derivatives of the s- and p-Block Metals

在这个由无机化学、生物无机化学和金属有机化学计划支持的项目中，哥伦比亚大学的Gerard Parkin将研究主要族金属化合物单体氢化物和烷基衍生物的探索性合成和机械方面的研究。这些化合物可用作选择性有机反应的试剂和形成陶瓷材料的前驱体。主要族金属(主要是镁、铝、锌和锂)将与大体积的三吡唑基硼酸盐配体络合，以确保它们的单体性质，并将合成氢化物、烷基、硅基、亚甲基(=Cr)、亚膦(=PR)、氧(=O)和硝基衍生物，并系统地研究它们的化学反应活性。这些研究将包括机理研究和寻找新材料、催化剂和陶瓷前驱体。

In this project supported by the Inorganic, Bioinorganic and Organometallic Chemistry Program, Gerard Parkin of Columbia University will investigate the exploratory synthetic and mechanistic aspects of monomeric hydride and alkyl derivatives of main group metal compounds. These compounds may have application as reagents for selective organic reactions and as precursors for the formation of ceramic materials. Main group metals (with emphasis on magnesium, aluminum, zinc and lithium) will be complexed with bulky tris-pyrazolylborate ligands to assure their monomeric nature and the hydride, alkyl, silyl, methylidene (=CHR), phosphinidene (=PR), oxo (=O) and nitrido derivatives will be synthesized and their chemical reactivity systematically investigated. These investigations will include mechanistic studies and the search for new materials, catalysts and ceramic precursors.
