这项工作详细介绍了反应性低配位有机锌配合物的合成，表征和催化活性。配合物活化氢，他们似乎是更积极的氢化酮和亚胺比他们的三齿钳类似物。这被认为部分是由于在以前的工作中缺乏第三个拖尾磷臂。DFT计算揭示了σ-键复分解机制与替代的芳构化/脱芳构化金属-配体协同机制相当。
This work details the synthesis, characterization, and catalytic activity of reactive low‐coordinate organozinc complexes. The complexes activate hydrogen and they appear to be more active in hydrogenation of ketones and imines than their tridentate pincer analogs. This is thought, in part, to be due to the lack of trailing third phosphorus arm present in previous work. DFT computations reveal a sigma‐bond metathesis mechanism is comparable to an alternative aromatization/dearomatization metal‐ligand cooperative mechanism.
