Abstract
Straightforward access to a cerium(IV)-carbene complex was provided by one-electron oxidation of an anionic "ate" cerium(III)-carbene precursor, thereby avoiding decomposition reactions that plague oxidations of neutral cerium(III) compounds. The cerium(IV)-carbene complex is the first lanthanide(IV)-element multiple bond and involves a twofold bonding interaction of two electron pairs between cerium and carbon.
摘要
通过一电子氧化阴离子“ate”铈(III)-卡宾前体，可直接获得铈(IV)-卡宾配合物，从而避免了中性铈(III)化合物氧化所产生的分解反应。该铈(IV)-卡宾配合物是首例镧系元素(IV)-元素多重键，涉及两个电子对在铈和碳之间的两倍键合相互作用。
