Synthesis and Reactivity of Transition Metal Hydrides

Michael Heinekey，化学系，华盛顿大学，由无机，生物无机和有机金属化学项目支持，继续探索金属-二氢相互作用或金属-烷烃相互作用。他使用独特的核磁共振技术，包括在核磁共振探针前体的光解；极低温核磁共振，交换偶联和氚核磁共振来探索这些弱键的性质。Heinekey还研究了细长的二氢配合物，这种配合物显示出新的振动和动态特性，可以提供氢键断裂过程的“快照”。未来科学家的教育和培训以及新的核磁共振方法的发展是这项工作的主要影响。氢的活化是生物（氢化酶）和工业上的一个关键反应。通过更好地了解各种金属与氢的相互作用，可以设计出更好的均相催化剂和工艺。

Michael Heinekey, Department of Chemistry, University of Washington is supported by the Inorganic, Bioinorganic and Organometallic Chemistry Program for continued explorations of metal-dihydrogen interactions or metal-alkane interactions. He uses unique NMR techniques including photolysis of precursors in the NMR probe; very low temperature NMR, exchange coupling and tritium NMR to explore the nature of these weak bonds. Heinekey also studies elongated dihydrogen complexes which display novel vibrational and dynamic properties that may provide a "snapshot" of an H-H bond rupture process. The education and training of future scientists and the development of new NMR methods are major impacts of this work. The activation of hydrogen is a critical reaction biologically (hydrogenase enzymes) and industrially. By better understanding how various metal species interact with hydrogen, better homogeneous catalysts and processes may be designed.
