Hydrohalogenation
Alkene + HX |
Markovikov addition
Peroxide (ROOR) gives anti-markovnikov Both are racemic mixtures |
|
Hydration
Alkene + (H30+) |
Proton transfer and markovnikov addition of water
|
|
Hydroboration Oxidation
1)BH3-THF 2)H202, NaOH |
Anti-markovnikov addition of water
Syn enantiomer of H and OH |
|
Catalytic Hydrogenation
H2/Pd |
Syn addition of hydrogen
|
|
Halogenation
X2 |
Adds best with Cl and Br, adds anti
|
|
Halohydrin
X2 + H20 solvent |
Water attacks more because it has higher concentration
It will attack the most substituted carbon |
|
Anti-dihydroxylation
RCO3H |
Creates epoxide, then water attacks anti
Creates 2 enantiomers |
|
Syn-dihydroxylation
OsO4/NMO & Na2SO3/H2O |
Creates Syn diol
Can also be achieved by KMnO4 under cold conditions MnO4- can further oxidize diols |
|
Oxidative cleavage
1) O3 2) DMS |
Cleaves by making =O bond between the alkene double bond
|
|
Oxymercuration-demurcuration
1)Hg+OAc, H20 2) BH4 |
allows markovinov addition of water without rearrangement
|
