Is there a photochemical synthesis of benzopinacol?
In this experiment it is aimed to synthesize benzopinacol through photochemical reaction of benzophenone and, benzopinacolone via acid-catalyzed rearrangement of benzopinacol. In this experiment, mixture of benzophenone, isopropyl alcohol and a drop of glacial acetic acid was exposed to sunlight which in turn, undergone photochemical reaction.
What happens when acetic acid is mixed with benzopinacol?
Subsequently, mixture of synthesized benzopinacol, glacial acetic acid and iodine crystal reacted in an acid-catalyzed rearrangement wherein dehydration of benzopinacol resulted into the formation of carbocation. In this state, an aromatic shifted and then, forming delocalized carbocation.
What was the yield of benzopinacol after the experiment?
Low yields were also obtained after the experiment as only 18.16 % ( 0.73g) benzopinacol and 21.88% (0.104g) benzopinacolone was collected. Photochemistry is the study of chemical reactions, isomerizations and physical behavior which occurs under the influence of visible or ultraviolet light.
How is benzopinacolone extracted from benzophenone crystals?
After cooling to room temperature, the white precipitate, benzopinacolone, was collected by vacuum filtration (Büchner funnel) and washed free of iodine using cold ethanol. The white benzopinacolone crystals were air-dried and analyzed by FT-IR using a PE 1600 Series spectrometer.
