Abstract
Phenyl groups were successively introduced at the bridgehead positions of c age compound HC(SiMe2SiMe2)(3)CH via deprotonation-cyclohexenylation-dehydr ogenation. UV absorption spectra of the cage compounds suggested the possib ility of electronic interaction between the cage and aromatic moieties. Bro mination of the phenylated cage molecule gave a p-bromo derivative that was transformed to liquid crystalline compounds.
