Abstract
Bromination (Br2, CCl4) of the anthracenone derivative (1b) under thermal or photochemical conditions gives the expected bromo-compound (1d) whereas photochemical bromination of the aryloxydifluoroboron complexes (2a, b) gives products (2c, d) of benzylic substitution; conversion of (2c) and (3a, b) into anthraquinone derivatives including madeirin (4) is described and extension of the regiospecific bromination procedure to the bicyclic ...
