Alcohols and Ethers 185 14.3 THE WILLIAMSON ETHER SYNTHESIS: PREPARATION OF PHENACETIN FROM ACETAMINOPHEN One of the most common methods used to prepare ether Williamson ether synthesis. In this reaction, an alkoxide anion (RO) acts as a nucleophile in an S, 2 process, displacing a leaving group (X) from an electrophile (R-X). R-20 . RY ROR...

How many products would you expect from the reaction of (S)-2-methylcyclohexanone with methyl magnesium bromide (include the stereoisomers)? Draw the stereoisomers of the product and specify the relationship between them. Following is a cyclic acetal formed from cyclohexanone. What are the reagents required for this reaction? Also write a stepwise mechanism for the formation of this acetal from cyclohexanone. Show how to synthesize the following compounds using a Wittig reaction. Design the synthesis of compound A (5-(1-hydroxycyclohexyl)pentan-2-one) starting from cyclohexanone...

Question- The second step is a name reaction. a) What is its name: b) Is it OK that we left the reaction in our drawer over the week? What would have happened if we didn’t have a good seal on the stopper? Draw a possible reaction scheme. Background The field of medicinal chemistry combines the specialties of synthetic organic chemistry and biology, and biochemistry. Compounds are generated and biological activity is screened using target specific assays. . These assays are...

6. Analysis Questions: a) This lab utilized a new technique called reflux, and the use of a condenser tube while heating the reaction. What is the purpose of the condenser? Why not just heat the reaction in a closed vessel instead? b) A student misread the instructions and first refluxed the sodium methoxide in...

How would you calculate % yield of intermediate A and the
final product diphenylacetylene? The mass of intermediate A
collected during the experiment was 74 mg and the mass of the
crystals (diphenylacetylene) was .162 g which is not feasible
however it is due to error as the filter paper wasn’t completely
dry yet. Included are pictures of all the chemicals used as well as
the procedure so you can see what was added to the reaction.
