Synthesis of \( \beta \)-Benzopinacolone: The Acid-Catalyzed Rearrangement of Benzopinacol The ability of carbocations to rearrange represents an important concept in organic chemistry. In this experiment, the benzopinacol, prepared in Experiment \( 54 \mathrm{~A} \), will rearrange to benzopinacolone (2,2,2-triphenylacetophenone) under the influence of iodine in glacial acetic acid. The product is isolated as a crystalline white solid. Benzopinacolone is known to crystallize in two different crystalline forms, each with a different melting point. The alpha form has a melting point of \( 206^{\circ} \mathrm{C}-207 . \mathrm{C} \), whereas the beta form melts at \( 182^{\circ} \mathrm{C} \). The product formed in this experiment is the \( \beta \)-benzopinacolone.
