| | 2,2'-Biimidazole Usage And Synthesis |
| Uses | 1H,1''H-2,2''-Biimidazole is used in the preparation of complexes that exhibits photoluminescence and optical properties. Also used in the preparation of bismuth biimidazoles as semi-conductors. | | Synthesis | 120 ml of distilled water was added to 1,092 g (14.2 mol, 4.0 eq.) of ammonium acetate at 40 ℃, 500 g of 20 wt percent aqueous glyoxal (3.45 mol) was then slowly added dropwise to the resulting slurry for three hours while stirring vigorously. Immediately after the addition was finished, the reaction mixture was neutralized with distilled water to adjust the pH to 5-7. The produced brown-colored solid was filtered and washed alternately with 500 ml of acetone and 500 ml of distilled water several times to obtain 82.0 g (53.2 percent yield) of 2,2'-Biimidazole.
