- The Meerwein-Ponndorf-Verley reaction involves reduction of a ketone by treatment with an excess of aluminum triisopropoxide, [(CH3)2CHO]3Al. The mechanism of the process is closely related to the Cannizzaro reaction in that a hydride ion acts as a leaving group. Propose a mechanism.arrow_forwardPredict the product(s) and provide the mechanism for each reaction below.arrow_forwardPropose a mechanism to account for the following transformation. H₂O+ HO OHarrow_forward
- Predict the product(s) and propose a mechanism for the following reaction. LOH H₂SO4 Heatarrow_forwardIn a strongly acidic solution, cyclohexa-1,4-diene tautomerizes to cyclohexa-1,3-diene.Propose a mechanism for this rearrangement, and explain why it is energetically favorable.Parrow_forwardIdentify the dominant elimination mechanism (E1 or E2) for the following reaction. NaOH Neither Е2 Е1arrow_forward
- The following compound undergoes Benzilic Acid Rearrangementto yield a hydroxyacid salt. Propose a mechanism for the reaction, write the major product, and provide an explanation as to the preference of migration of one R group over the other.arrow_forwardPropose a detailed mechanism for the following reaction: HO ye OH H₂SO4arrow_forwardPropose a mechanism and predict the products for each reaction. For reactions where more than one product can form, draw all possible products and predict which would be the major product.arrow_forward
- When the following compound undergoes solvolysis in ethanol, three products are obtained. Propose a mechanism to account for the formation ofthese products.arrow_forwardPropose a plausible synthesis for each of the following transformations:arrow_forwardTestosterone is one of the most important male steroid hormones. When testosterone is hydrated by treatment with acid, rearrangement occurs to yield the product shown. Propose a mechanism to account for this reaction.arrow_forward
