Can you explain the mechanism for the elimination reaction with 2,3-dibromo-3-phenylpropanoic acid + aqueous NaCo3/H2O to yield beta-bromostyrene.
Homework Answers
In protic solvent it will undergo E1 elimination to form beta-bromostyrene
In Protic solvent alpha carbon attached C-Br bond undergo electrolytic cleavage to form carbocation
followed by abstraction acidic proton by base and undergo decarboxylation to form final product.

Can you explain how the J values on HNMR support an E or Z configuration as it relates to the reaction of 2,3-dibromo-3-phenylpropanoic acid with acetone as the solvent, then with water as the solvent, to yield Beta-Bromostyrene. J values for Acetone give a ratio of 1:2 98%-cis 2%-trans. For Water it's 1:4 20%-cis, 80%-trans. Thank you.

Draw a proposed mechanism for the reaction of cyclohexanol with aqueous sulfuric acid to yield cyclohexene. Label each step as either: nucleophilic attack, loss of a leaving group, or proton transfer. What type of elimination reaction is this: E1 or E2? Explain. Explain how the leveling effect has occurred in this reaction? What is the likely base in the last step: water or HSO4-? Explain.

prelab wants me to draw a mechanism for both pairs. so one
mechanism for the 93-95 C pair and another mechanism for the
202-204 C pair. Please draw out full mechanism with arrow pushing
please for both!
trans-cinnamic acid Bromination of trans-cinnamic acid can result in the formation of two different pairs of enantiomers (see Figure 4). Fortunately, the pairs of enantiomers have very different melting points. Thus, we can determine the result of this reaction by examining the melting...

What is Zaitsev’s rule? Give the mechanism for the acid-catalyzed E1 reaction of 2-butanol. Give the mechanism for the base-catalyzed E2 reaction of 2-bromobutane. Draw all possible products. You expect three products from the elimination reaction 2-butanol. What are they? The E2 mechanism is a one-step mechanism. True or False? Explain. Which of these two alcohols would you expect to be more reactive under H3PO4/aqueous conditions? Why? Give the structure of the main product in both cases. 1-phenyl-1-propanol 1 -cyclohexyl-1-propanol...

Hello, I have a question about my post lab report. I used .1g of trans-3-phenyl-2-propanoic acid and 1.5mL of methylene chloride. Later I added 0.8mL of 1M bromine solution to it. I ended up getting the anti stereoisomer of 2,3-dibromo-3-phenylpropanoic acid. The product that I ended up weighing out was 0.0380g. Can you please calculate out the % yield for it? Thanks!
The product was 2,3-dibromo-3-phenylpropanoic acid, with a
melting point of 198-200 °C . So a racemic mixture of (2R,3S) and
(2S,3R).
