Coordination of Buckybowls:The First Concave-Bound Metal Complex

摘要

The discovery of fullerenes has opened up a new research area in organometallic and coordination chemistry:the study of metal binding to nonplanar pi-carbon surfaces.As a result,a great number of exohedral transition-metal complexes of fullerenes have been synthesized over the last two decades.111 In contrast,the controlled synthesis of endohedral fullerene complexes by chemical methods is still lacking.Only a limited number of metal centers have been encapsulated in fullerene cages by arc-evaporation of graphite-metal composites at high temperatures.
