Draw the mechanism for the conversion of propanedial in its keto form to its enol form under basic and acidic conditions. Do the same for the conversion from the enol form to the keto form.
4. Conversion of B into C involves hydrolysis of the ester followed by decarboxylation. On the structures provided below, show the electron flow for the decarboxylation step. CH2Ph 5. The initial product formed on decarboxylation is an enol, which rapidly equilibrates to its keto form under the acidic reaction conditions. Write the complete stepwise mechanism for the acid-catalyzed conversion of the enol into its keto form, Compound C. Ph Ph
4. (15 Points) Pericyclic Reactions: The transformation below can be described as a pericyclic reaction followed by a polar-acidic mechanism, where the acid is not shown because it is picked up from the environment. (a) Start by redrawing the starting material below, and show how the pericyclic reaction occurs with curved arrows. (b) Specify the type of pericyclic reaction it represents and the name reaction. (c) If you've done the pericyclic reaction correctly, your product will be an enol. From...
Pre-lab exercise: Below is the structure of the imine product. It is depicted in its most stable enol form. However, it will be important to consider the keto forms of this molecule for understanding its photophysical properties. Predict the structure of a keto form, and draw the mechanism for this isomerization from the enol form. (Hint: the keto form is created through a hydrogen transfer from the alcohol to the imine N, resulting in formation of an amine, a ketone,...
Experiment #6: Saponification of Wintergreen Oil 1.) Draw a reaction mechanism for the conversion of wintergreen oil into salicylic acid. 2. ) If you wanted to take an IR spectrum to confirm that the reaction worked, what would you look for in the spectrum? 3.) It is also possible to hydrolyze an ester under acidic conditions. Draw a mechanism for the acid-catalyzed conversion of wintergreen oil to salicylic acid.

Hydration of alkenes under aqueous acidic conditions. Draw the detailed stepwise mechanism for this reaction. Be sure to show all steps, intermediates, formal charges, and show the movement of electrons with curved arrows. You do not need to draw transition states. H2SO4 H20 ?? The hydration of alkynes can also occur under aqueous acidic conditions however, instead of forming the alcohol, a ketone is formed. Draw the detailed stepwise mechanism for the conversion of the alkyne to the ketone (one...
