1,4-二苯基-2-丁炔-1,4-二酮

反应条件: temp:30.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: 1,2-bis(benzoyl)acetylene (C16H10O2, 234.27, 2 g, 8.54 mmol), tetraphenylcyclopenta-dienone (C29H20O, 384.47, 3.28 g, 8.54 mmol), and 40 g benzophenone were refluxed for 2 hr under an atmosphere of nitrogen. The reaction mixture was cooled to 30° C. and poured into a large volume (250 ml) of methanol. The tan precipitation was washed with methanol (2×10 ml) and refluxed in toluene (25 ml) charcoal (a spoon) to give a white crystal in 43% yield.
