Benzannelated 9-Hydroxyphenalenones
Haddon, R. C.
, p. 1733 - 1738 (2007/10/02)
The preparation and characterization of the two title compounds (6-hydroxybenzanthracen-7-one (2) and 3-hydroxybenzanthracen-4-one (3) or their proton tautomers), and an isomer (8-hydroxybenzanthracen-7-one (4)), are reported.The electronic spectra of (2) and (3) suggest that annelation of 9-hydroxyphenalenone (1) produces substantial shifts in the energies and intensities of the transitions, but does not fundamentally alter the underlying character of the chromophore.
