The first heterobimetallic Pd-Sc complex featuring a very short Pd→Sc dative bond has been synthesized and characterized by multinuclear NMR spectroscopy, X-ray diffraction analysis, and electrochemistry. Computational studies elucidated the nature of the Pd→Sc bond as a donor-acceptor interaction, which generates a more electron-deficient Pd metal center as compared to that in the mono Pd complex in their reactions with isonitrile and carbon monoxide. Cooperative reactivity has been demonstrated in the reaction with MeI.
首个具有极短钯→钪配位键的异双金属钯-钪配合物已被合成，并通过多核核磁共振光谱、X射线衍射分析和电化学进行了表征。计算研究阐明了钯→钪键的本质是一种供体-受体相互作用，与单钯配合物在与异腈和一氧化碳反应时相比，这种相互作用会产生一个电子更缺乏的钯金属中心。在与甲基碘的反应中已证明了协同反应活性。
