Draw the full reaction mechanism for a wittig reaction of using benzyl chloride, triethyl phophite, sodium methoxide, and p-methoxybenaldehyde to form the product (p-methoxystilbene). How would you monitor this reaction? How could you tell if this reaction was successful? How do you recrystalize p-methoxystilbene?

sketch the reaction mechanism and inlcude the final
product.
MRU: Before meeting with your partner, sketch the reaction mechanism (including the final product) corresponding to the following description. Be prepared to explain the mechanism to your partner. o o 4-methylpentan-2-one is reacted with potassium cyanide followed by hydrochloric acid. (set up the reaction - next you will get a description of the mechanism to draw). The lone pair of electrons on the cyanide carbon will react with the partial positive...

CONCEPT QUESTIONS Mechanism. While the reaction carried out in lab used potassium hydroxide as the catalyst, many other catalysts have been developed to increase regioselectivity and stereoselectivity in aldol condensations. One small molecule catalyst commonly used is proline, a naturally occurring amino acid. a The mechanism involves the initial formation of an enamine; predict the structure of this enamine intermediate (intermediate Al and draw the mechanism for the conversion of intermediate A to intermediate B. Helpful Hint: The formation of...

Based on the Wittig Reaction exp. below, please answer a) and
b). In b) you can disregard the part about the IR, just please
interpret and assign protons, shift values, which protons are for
which groups, etc on the HNMR. The % yield was 34%, and MP was
lower than expected (to assist with answering part a). This should
be all the information you need to answer the question.
