Abstract:
Much higher reactivity of [Li(+)@C60]PF6(-) for Diels-Alder cycloaddition toward cyclopentadiene (CpH), in comparison with that of empty C60, was observed. The synthetic method, electrochemical and light absorption properties, and X-ray crystal structure of the product [Li(+)@C60(CpH)]PF6(-) are discussed.
