In the reaction of
4-Nitrobenzaldehyde + Acetophenone -> trans-4-Nitrochalcone
a. The yield of the reaction to form your chalcone is not quantitative. What side
products might be formed from your aldol condensation?
b. If one uses benzaldehyde rather than p-nitrobenzaldehyde in the aldol reaction the yield is extremely low, if it works at all. Offer an explanation for this result.
In the bromination of
a racemic mixture forms
b. Will you see 2 spots on a TLC of your reaction products? Why or why not?
c. Is your bromination reaction stereoselective? Why or why not?
Aldol reactions are analyzed. Racemic mixture forms are examined.
