1. The Wittig reaction is one method used by organic chemists to synthesize alkenes, You have leamed that alkenes can also be synthesized from alkyl halides and alcohols. Write an equation to show which alkenes can be made from the following compounds and indicate the conditions (reagents, catalyst, temperature) needed to carry out the reaction in good yield. a. 2-bromo-1-phenylpropane b. 3-methyl-2-pentanol 2. For the reaction you have done, what was the theoretical yield in grams of 1,4-diphenyl-1,3-butadiene? Show calculations. What was the percent yield of the 1,4-diphenyl-1,3-butadiene? Show calculation. 3. Draw the structure of the alkyl halide to prepare each of the following Wittig reagents and then determine which Wittig reagent will more difficult to prepare. Explain your choice. 4. Elizabeth Colby Davie from Assumption College reported the development of a laboratory experiment in which students reacted 1,4-diphenyl-1,3-butadiene with dimethylacetylene dicarboxylate (J. Chem. Educ., 2015, 92(7), pp 1209-1213). Draw the product and provide the mechanism for this reaction. 5. The structure of the sex pheromone of the female tsetse fly has been confirmed by the following synthesis. Compound Z appears to be identical to the natural pheromone in all respects (including the response of the male tsetse fly). Provide structures for X,Y, and Z
