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?
Homework Answers
You could monitor this reaction
by TLC observing the disappearance and appearance of reactive and
product respectively. You can tell if it was successful by
calculating the theoretical yield (major of 60- 70 %) (you have to
weight the product and do an stechiometric calculation)
You can recristalize it in hot ethanol. Dissolve the p-methoxystilbene in the minimun amount of hot ethanol and left to cool slowly. Filter.

1) Draw the complete mechanism of the Wittig reaction of benzyltriphenvlphosphonium chloride with 9-anthraldehyde where potassium hydroxide is used as the base. 2) In the reaction from question 1, what are the two stoichiometric byproducts? Hint: One is inorganic (contains no carbon atoms) and doesn't contain oxygen. The other byproduct is organic (does contain carbon atoms) and does contain oxygen. Identify them in your mechanism above

How would you prepare benzyl methyl ether using a Williamson ether synthesis? The list of reagents to choose from are: 2-Chloro-norborane, Benzyl chloride, 2-Chloro-2-methylpropane, 4-Chloro-1-butanol, and Chlorobutane. I was reading online and it kept mentioning SN2 reactions, using an alcohol, and an alkyl halide for the synthesis. My guess would be using Benzyl Chloride and another one with an OH attached, but I could be completely wrong. Please help and explain by showing the reaction mechanism. Thank you so much!...

Please write out full reaction mechanism: Iron (II) chloride tetrahydrate and iron (III) chloride hexahydrate will be dissolved in deionized (DI) water to form a homogeneous solution. The solution will then be heated in a water bath at 65°C for 15-20 minutes; followed by the addition of 25% sodium hydroxide. Please write full chemical formula (step by step + explanation) so that I can understand. Please write legibly if handwritten. Thank you so much!
