What is a detailed mechanism for the bromination of trans-stilbene with Br2.
conversion of stilbene to diphenylacetylene
Report Questions: What would you get as a product in Part A if cis-stilbene was used instead of the trans-stilbene? (Draw and think about the mechanism of the reactionl) Draw the proposed product with appropriate stereochemistry. Assign the chirality of the chiral centers. (Are these of the same absolute chirality when using trans-stilbene?) Is this a meso compound? Would this compound form the er same product as in Part B? Explain your answer.
Draw the reaction and reaction mechanism for the reaction of
both
cis
and
trans
stilbene with Br2
as part of your prelab procedure.
Note: I'm not sure what the
mechanisms look like so that's why I'm having trouble with the
products. Please, if you can, draw out the mechanisms for both of
these!! Thanks.
cis-stilbene trans-stilbene
9.58 (*) Enantioselective epoxidation of trans-stilbene using the Jacobsen catalyst results in an optically active epoxide. On the other hand, when the same conditions are utilized with cis-stilbene as the substrate, the product is optically inactive. Explain this observation H HI =N Mn S,S-Mn-salen NaOCI 80% yield optically active (S,S)-Mn(II)-salen
What is the lewis dot structure of trans-stilbene?
alswering these questions. 1. If the bromination of trans-stilbene proceeded by syn addition what isomer(s) of stilbene dibromide would be formed? 2. If the bromination of trans-stilbene proceeded by anti addition what isomer(s) of stilbene dibromide would be formed? 3. Which isomer(s) of stilbene dibromide would be formed if the reaction followed Mechanism 4? Mechanism 4: Bromination is a multi-step process. In this mechanism, the pi bond attacks the bromine molecule as in Mechanism 1. Some time after the carbocation...
What is the product of the reaction of benzene with 2-chloro- 2-methylpropane in the presence of AlCl3? Answer: isopropylbenzene
What is the theoretical yield for the bromination of trans-Stilbene reaction? Setting up the experiment: 18mg of trans-Stilbene and 103mg of polymer supported brominating agent & 2mL chloroform Monitoring the experiment: 5mg of trans-Stilbene in 1ml of Chloroform
