Fundamental Organometallic Transformations

约瑟夫·邓普顿，北卡罗来纳大学教堂山分校化学系，由无机化学、生物无机化学和有机金属化学计划支持，继续他对过渡金属配位配体的基本反应的研究。这笔赠款的一个重点是含有配位卡宾或卡宾的钨配合物。像Tp‘i(O)W=C(CH3)(OSiR3)这样的络合物，其中Tp’代表三吡唑基硼酸酯，是与高氧化态金属结合的“Fischer类型”卡宾的不寻常的例子。研究将探索这些物种的成键和反应能力。该基金的另一个重点是合成与碳氢键活性有关的铂(IV)有机金属配合物。对这些配体的电子结构和成键的基础研究有助于深入了解重要的多相催化过程。此外，研究生和博士后助理将在合成、表征和反应性研究方面学习宝贵的技能。

Joseph Templeton, Department of Chemistry, University of North Carolina at Chapel Hill, is supported by the Inorganic, Bioinorganic and Organometallic Chemistry Program to continue his studies of fundamental reactions of ligands coordinated to transition metals. One focus of this grant involves tungsten complexes with coordinated carbynes or carbenes. Complexes such asTp'I(O)W=C(CH3)(OSiR3), where Tp' represents a tris-pyrazoyl borate, are unusual examples of "Fischer-type" carbenes bound to a high oxidation state metal. Studies will probe the bonding and reactivity of these species. Another focus of the grant is the synthesis of organometallic complexes of Pt(IV) relevant to carbon-hydrogen bond activation.Fundamental studies of the electronic structure and bonding of these ligands provide insight into important heterogeneous catalytic processes. In addition, graduate students and postdoctoral associates will learn valuable skills in synthesis, characterization and reactivity studies.
