Abstract. Hexasubstituted benzenes are of potential interests as polypodands, host molecules and disc-like molecules. They are prepared by catalytic cyclotrimerizat, ion of disubstituted alkynes 1-8 or by nucleophilic substitution of bromine in hexakis (bromomethy1) benzene 9-17. The different methods of preparation were compared. The new hexasubstituted benzenes were characterized by some chemical and physical ...
