Fundamental Organometallic Transformations

查佩尔山的北卡罗来纳州大学化学系的Joseph Templeton得到了无机、生物无机和有机化学项目的支持，继续研究与过渡金属配位的配体的基本反应。该补助金的一个重点涉及钨配合物与协调卡宾或卡宾。诸如Tp 'I（O）W=C（CH 3）（OSiR 3）的络合物，其中Tp'代表三-咪唑基硼酸盐，是与高氧化态金属结合的“Fischer型”卡宾的不寻常的例子。研究将探索这些物质的键合和反应性。资助的另一个重点是合成与碳-氢键活化相关的Pt（IV）有机金属配合物。这些配体的电子结构和键合的基础研究为重要的多相催化过程提供了深入了解。此外，研究生和博士后将学习合成，表征和反应性研究的宝贵技能。

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.
