The Uses of 1,4-Diacetylbenzene
1,1''-(1,4-phenylene)bis-Ethanone can undergo oxidative C-C Bond Cleavage to synthesize an aryl carboxylic acid with an iodine catalyst . 1,1''-(1,4-phenylene)bis-Ethanone is also capable of Suzuki-Miyaura coupling.

Purification Methods
Crystallise it from EtOH (m 114o) or *benzene and dry it in a vacuum over CaCl2. Also purify it by dissolving it in acetone, treating with Norit, evaporating and recrystallising from MeOH. The dioxime has m 248-259o. [Wagner et al. J Am Chem Soc 108 7727 1986]. [Beilstein 7 H 686, 7 II 624, 7 III 3504, 7 IV 2156.]
