摘要：

The synthesis of 2.3-dibromobenzonorbornadiene ene 11 by high temperature bromination of 2-bromobenzonorbornadiene 9 allows the synthesis of the benzoannelated trimers, syn- and anti-5,18:6,11:12,17-trimethanotrinaphthylene 8. The syn isomer is a basket shaped molecule that displays unusual geometric and electronic features including bond length fixation of the central benzene ring as shown by X-ny diffraction (exocyclic bond 1.41 Angstrom, endocyclic bond 1.36 Angstrom).
