The reduction of ethyl acetoacetate with sodium borohydride is
show below. Explain why the product of the reaction does
not have two alcohol functional groups.
QH NaBH4 ethanol, 0°C
write the mechanism for the hydrolysis of ethyl acetoacetate in an acidic environment and the decarboxylation of the acetoacetic acid product.
What reagent might be added to phenylmagnesium bromide to produce methyl phenyl ketone? (Hint: ethyl acetate is not a good choice.) Draw the mechanism for this reaction
Draw the product of ethyl acetoacetate, base, 3-bromopentane, hydrolysis and heat.
Provide the stepwise mechanism for the reduction of butanal with LiAlH4 in THF.
The reaction is the Pechmann reaction of resorcinol and ethyl acetoacetate to form 4-methylumbelliferone: When HCl is added to the product, protonation occurs at the carbonyl oxygen of the ester. Draw the conjugate acid of this reaction and explain why 4-methylumbelliferone is more basic than a typical ester. Note: my professor mentioned something about Lewis acids/bases and mentioned how bases are more electron rich. I would like to explain how the product is more basic than a typical ester using...
Propose a mechanism for the reduction of ethanoic acid (acetic acid) by LiAlH4 to generate ethanol.
Give three methods for the reduction of a ketone and provide a
mechanism for at least one of your chosen methods

A
co₂Et 4. A Chem 241 student was given an experiment to synthesize compoun OH acetoacetate. The student prepared 1 mole equivalent of methylmagnesium lo which was then slowly added to a solution of ethyl acetoacetate in ether. Every 1 went well, Indeed, even without the annlication of heat the reaction mixture Dubbie orking carefully, with supervision and advice from the lab instructor, the student worked- up the reaction and isolate - LII Caction and isolated an excellent vield of...
