Abstract
The use of substituted cyclooctatetraenes confers various desired properties on the resulting metal complexes such as a higher thermal and kinetic stability as well as higher solubility relative to the nonsubstituted systems. Furthermore, the formation of polymeric structures is inhibited because intermolecular interactions are reduced. Alkyl- and aryl-substituted cyclooctatetraenes were mainly used as ligands in the 1970s and 1980s. The vast majority of known complexes containing these ligands in the coordination sphere are uranium compounds. Since then the alkyl- and aryl-substituted cyclooctatetraenes have been replaced almost exclusively in synthesis by silyl-substituted ones. Complexes with silyl-substituted cyclooctatetraenes are known for both 4f and 5f elements.
