2,9-dibromo-13,13-dimethyl-11,13-dihydro-6H-indeno[1,2-b]anthracene-6,11-diol → 2,9-dibromo-13,13-dimethyl-6H-indeno[1,2-b]anthracen-11(13H)-one

Participants

Reaction Steps

2,9-Dibromo-13,13-dimethyl-11,13-dihydro-6H-indeno[1,2-b]anthracene-6,11-diol (15 g, 1 eq, 0.003 mol) was placed in a flask, and 5N HCl (100 ml) was added thereto. The reaction mixture was stirred for five hours while heating. The resultant solid was filtered, several times washed with distilled water and dried to give 2,9-dibromo-13,13-dimethyl-6H-indeno[1,2-b]anthracen-11(13H)-one (13.2 g, yield=92%).
