在这一进展报告中，描述了合成具有迄今未知结构特征的多金属π‐配合物的新原理。镍(0)-烯烃配合物1,5,9 -环十二十烯镍(0)和二（1,5 -环二烯）镍(0)与主族金属，特别是碱金属及其氢化物和有机金属化合物发生意外反应，产生带多余电荷的镍配体。这些物质努力将多余的电荷转移到π -配体上，如烯烃或二氮。此外，具有富电子过渡金属π -配体单元的多金属配合物也可以由茂金属、碱金属和不饱和化合物制备。本文将对这类新物质的合成、结构和反应进行综述。
In this progress report a new principle is described for the synthesis of multimetal π‐complexes with hitherto unknown structural features. The nickel(0)‐olefin complexes 1,5,9‐cyclododecatrienenickel(0) and bis(1,5‐cyclooctadiene)nickel(0) react unexpectedly with main‐group metals, in particular alkali metals, their hydrides, and organometallic compounds, to give nickelligand species with a surplus charge. These species endeavor to transfer the excess charge onto π‐ligands such as olefins or dinitrogen. Multimetal complexes with electron rich transition metal π‐ligand units can, in addition, be prepared from metallocenes, alkali metals, and unsaturated compounds. The syntheses, structures, and reactions of this new class of substances will be summarized.
