Instructions: The products shown can be prepared from the given starting materials, inorganic reagents, and additional compounds described in the problem. Your problem set answers must be on this problem set when you turn it in, and not on separate sheets of paper. I have included the number of steps needed using the synthetic route that I have identified, but other routes may be possible. For each problem, show the product after each step, and include all reagents. You do not need to supply mechanisms. 4. 2 steps. Use an organometallic reagent to add the additional carbon 5. 2 conversions, 1 step each: Show both a Heck reaction and a Suzuki coupling reaction that would convert bromobenzene to vinylbenzene. Br 6. 3 steps: You can choose a 1-carbon compound to add the additional carbon. 7. 3 steps: Only use chemistry that does not require extreme heat (such as >200*C), and you may choose an amine to use in your synthesis CH3 CH3
