The accepted mechanism for a rearrangement reaction is shown below. "Q Ph (1) (ii) Ph Ph HO™ fast Ph Ph HO O™ slow Ph aufae .Ar² LOH HO™ fast Draw a curly arrow mechanism for this transformation. Sketch an energy profile for this reaction, showing approximate relative energies for the reactants, intermediates, transition states, and products. HQ Ph (iii) When DO™ was used as the reagent, the rate of product formation was same as for HO™. Explain why this result shows that the third step is fast and cannot be rate-determining. Ph (iv) Write the predicted rate equation for this mechanism, and show how it was derived. (v) The starting diketone may have two different aryl groups, as shown below. Propose a ¹³℃ labelling experiment that would allow you to distinguish which of the two aryl groups had migrated in this situation. OH AR²0- Ar¹ C C
