Spectral Characterization of Anthracene-, Cyclopentadiene-, and Dichlorocarbene-C60Adducts

Abstract
We studied cycloaddition reactions of C60 with typical dienes and dichlorocarbene. The title products were isolated by HPLC and characterized by negative ion FAB mass spectroscopy. 13C NMR analyses suggest that all of the adducts investigated here have the closed structures at the 6-ring/6-ring junction.
