1.) Stilbene is synthesized through the Horner-Wadsworth-Emmons reaction, which is closely related to the Wittig Reaction. Draw out the starting materials for the stilbene synthesis through the Wittig reaction. Give one aldehyde compound and one ylide compound as the starting material 2.) For the previous question, give a detailed arrow-pushing mechanism for the ylide formation. 3.) Starting from the ylide and aldehyde from question 1, draw a detailed arrow-pushing mechanism to give benzil.
Stilbene is synthesized using the Wittig reaction. What is the starting aldehyde and ylide compound in the reaction? Show the mechanism of the ylide formation and then show the mechanism, using the same ylide and aldehyde, to create benzil.

To perform the Wittig reaction, one must first synthesize a
phosphonium ylide. Draw a stepwise mechanism for the phosphonium
ylide formed from triphenylphosphine (represented as simply PPh3)
and 2‑bromobutane. Then draw the resonance structure of the ylide
product.
To perform the Wittig reaction, one must first synthesize a phosphonium ylide. Draw a stepwise mechanism for the phosphonium ylide formed from triphenylphosphine (represented as simply PPhz) and 2-bromobutane. Then draw the resonance structure of the ylide product. Ph CH3CH2CHBCH3 → n-Buli...
To perform the Wittig reaction, one must first synthesize a phosphonium ylide. Draw a stepwise mechanism for the phosphonium ylide formed from triphenylphosphine (represented as simply PR3, below) and 2-bromobutane. Then draw the resonance structure of the ylide product.
Please help.
The Wittig reaction involves coupling between a phosphonium ylide and a carbonyl-containing molecule. If a chemist wants to use the Wittig reaction to synthesize xene, which reactants should be used? Use the graded interactive module below to explore the reactivity and mechanism of the Wittig reaction and to construct the target product molecule. Click and drag a reactant molecule from each column onto the reaction stage. Note the mechanism of the reaction and the obtained products. After constructing...
Wittig Reaction Lab: Provide the appropriate Wittig product(s) formed from the following starting materials [assume the addition of aqueous sodium hydroxide in order to create the reactive ylide intermediate]. Clearly indicate any chiral centers and E/Z isomerism: a) o-methylbenzaldehyde, triphenylphosphine, and (R)-1-bromo-2,3-dimethylbutane b) (S)-1-chloro-3-ethylhexane, triphenylphosphine, and cyclopentanone
This is the Wittig reaction (synthesis to make E and Z
stilbenes)
This is for the Wittig Lab of Organic Chemistry 2. Please answer
to all 3 questions with explanations as simple and specific and
possible to understand.
