a. First, circle the leaving group and label the alpha carbon as a. b. Then, label the adjacent sp3 beta carbons as B. c. Finally, draw in the H’s that can get eliminated along with the leaving group in each of these compounds. The first compound has been completed for you. HH می ) و CH3 2. Now, let’s perform the elimination to make the Zaitsev (most substituted) product. Draw in the H from before and the curved arrows to explain electron movement. Use B: as a generic base. :B HH Vac H CH The scent of cinnamon is biosynthesized from the amino acid phenylalanine. Draw a mechanism for this E2 elimination and provide the structure of trans-cinnamic acid. Note the departing groups drawn under the reaction arrow. [email protected] – NH3 One method to degrade the fluorinated environmental pollutants (PFOAs, etc.) is to use radical chemistry to eat away at the carboxylic acid end of the molecule. Provide an arrow pushing mechanism for this intermediate step (box 1 to box 2) in the process. (We’ll do the full mechanism in a later HW!)
