Electrophilicsubstitutionreactions of sumanene were studied. Mono-, di-, and trisubstituted sumanenes were selectively prepared with the separation of all regioisomers. The regioselectivity was p...
is a bowl-shaped pi-conjugated molecule with C3v symmetry, consisting of alternating benzene rings and cyclopentadiene rings around the central benzene ring. The structure corresponds to the smallest C3v-symmetric fragment for the structural motifs of fullerenes or end-caps of carbon nanotubes. The presence of three sp(3)-hybridized benzylic sites is one of the most characteristic structural features
