2. Starting with 2-methyl-1-phenylpropan-1-one, show how you can convert this to 2-methyl-1- phenylpropan-1-ol. What reagent did you choose and why? Show all steps and draw the product. Is this addition to benzene an activator or deactivator? 3. Using the product from step 2. Show how using the tosyl chloride reagent from the alcohol reactions powerpoints how this can be converted to this molecule, isobutyl benzene: Is this addition to benzene an activator or deactivator?

Without using wolff kishner reduction, complete this multistep synthesis with steps, including the reagent used and the products at each step.

1. Show the steps necessary to make this compound using a Wittig reaction. Start with triphenylphosphine and an alkyl halide. After that you may use any other organic or inorganic reagents CH₂

What is the proper reagent for this transformation?

1. Propose multi-step syntheses to make the products shown below. Separate the steps with numbers. You should think about the product after each step you propose to make sure the scheme will work. Use the summary of reactions at the end of Ch 8,9, 10, 11, 17 to help you. Count the number of carbons in the reagents and products. A) OH .CI B) ??? HO. C) H2 .C ??? CH3 CH3CCCH3 H3C `CH3 Но

4. Write in the reagents that will accomplish the following transformation. Reagents must be placed in the correct order. Show products formed after each step. ?? Br b Br

a. Show the major product for the reaction shown and a mechanism for its formation. Do not use any termination steps in your mechansim .. only propogation steps. Br2 hv b. If sufficient bromine is added and the reaction is allowed to proceed further, another product will form from the first. Show a mechanism for the reaction of the product from part a. to form the final product with two bromines attached.

2. Starting with 2-methyl-1-phenylpropan-1-one, show how you can convert this to 2-methyl-1- phenylpropan-1-ol. What reagent did you choose and why? Show all steps and draw the product. Is this addition to benzene an activator or deactivator? 3. Using the product from step 2. Show how using the tosyl chloride reagent from the alcohol reactions powerpoints how this can be converted to this molecule, isobutyl benzene: Is this addition to benzene an activator or deactivator?
