An improved synthesis in described for the dibenzazonine precursor of erysodienone.Other biphenyl-4,4'-diols, bridged by two, three and five atoms, were also prepared.E.s.r. examination of the oxidation of these compounds produced spectra of the 9,10-dihydrophenanthrene-4,4'-semiquinone system, hitherto unrecorded, but semiquinone spectra could not be obtained from the other diols.
