Homework Help: BH3 * THF vs. HBr/ROOR

  1. Jan 19, 2015 #1
    1. The problem statement, all variables and given/known data

    What series of steps could be used to carry out the transformation shown below

    2. Relevant equations

    but-1-ene → Butyl cyanide

    3. The attempt at a solution

    This is a practice problem, so I already know that the answer is 1) HBr + Peroxide, 2) NaCN, but could it not also be BH3*THF and NaCN? My guess as to why that might not work is because Br is a much better leaving group than the boron group, but I just wanted to be sure.
