Assembly of Reaction Place by Using High Valent Metal Hydride Complexes

在这个项目中，我们计划探索高价金属氢化物的化学。芳氧基衍生的多齿支持配体的使用使我们能够在高氧化态下分离出各种早期过渡金属的氢化物配合物。我们发现这些缺电子的氢化物络合物能够激活小分子。例如，一个钽氢化物络合物经历了CO的C-O键断裂，然后C-C和C-H键的形成，导致了苯硝酸酯络合物的形成。

In this project, we have planned to explore the chemistry of high valent metal hydride complexes. The use of aryloxide-derived multidentate supporting ligands allows us to isolate a variety of hydride complexes of early transition metals in high oxidation states. We found that these electron-deficient hydride complexes are capable of activating small molecules. For example, a tantalum hydride complex undergo C-O bond cleavage of CO followed by C-C and C-H bond formation, resulting in formation of an ynolate complex.
