    adds a Br to stabilized carbocation spot
  2. What does 1. Li 2. CuI 3. R-Br do?
    removes an I(halogen) and attaches R group
  3. What does 1. Li 2. B(OEt)3 do?
    removes a halo and replaces with B(OEt)2 group
  4. What does PdL2/OH- do?
    removes B(OCH3)2 and adds a double bond with the Br on the given product (CH2=CHBr)
  5. What does 1. Mg 2. CH3OH do?
    removes the halo and hydrogenates
  6. 1. Mg, Et2O
    2. ethyloxycyclo (triangle with O in it)
    3. H+, H2O
    with halo forms cyclo, halo end gets Et2 group, other end gets OH
    adds Br group to any possible places while keeping the double bond
  8. HBr/ROOR
    adds Br to where double bond is
  9. Cl2/hv
    adds Cl to unstablized carbocation
  10. PdL2/Et3N
    attaches given double bond group
  11. Mg/triangle O group
    replaces halo with # of carbons and a OH not at end
  12. PdL2, OH-
    and a B(CH3O)-R
    attaches double bond of R group to where the B(OCH3)2 group is
  13. HBr/ROOR
    removes double bond and replaces with Br
  14. 1. HBr
    2. Li
    3. CuI
    4. CH3I
    removes double bond from cyclohexene and places R group in that spot
  15. 1. HBr, ROOR
    2. NaCN
    adds a CN group at end
