摘要
The reaction of the previously reported anionic aluminabenzene with zirconium chlorides (CpZrCl3, Cp*ZrCl3, and ZrCl4) gave novel zirconium complexes bearing aluminabenzene ligand(s). The X-ray crystallographic analysis of the resulting complexes revealed that the aluminabenzene ligand(s) coordinated to the zirconium center in an eta(5)-fashion as a six-electron donor. Chloride ligand(s) on the zirconium center intramolecularly coordinated to the Lewis acidic aluminum atom in the aluminabenzene ring. The variable-temperature H-1 NMR experiment showed a dynamic process for dissociation and recoordination of chloride to the aluminum center.
