Reaction Steps

3,6-Dibromoanthrone, a tuned photoinitiator precursor, can be prepared by first producing 2,7-dibromoanthraquinone by the direct bromination of anthraquinone with elemental bromine under pressure at about 160° C. as described by Diehl, Chem. Ber, 11, 1878, p181. The dibromoanthraquinone is then reduced to the 3,6-dibromoanthrone with aluminum metal and sulfuric acid as described by R. Biehl, et al., J. Amer. Chem. Soc., 99(13), 1977, pp.4278-4286.
