| Question | Answer |
|---|---|
| Oxy-demercuration | Hg(OAc)2, H20 / NaBH4, NaOH **alkene to alcohol Markovnikov |
| Hydroboration | BH3, THF / H2O2, NaOH **alkene to alcohol anti-Markovnikov |
| Bromohydrin | Br2, H2O **ANTI addition, Br to least substituted |
| Full hydrogenation | H2, Pt |
| Partial hydrogenation (cis) | H2, Ni2 or H2, Pd/CacCO3/quinoline |
| Partial hydrogenation (trans) | Li/NH3 |
| Hydroxylation | OSO4/NaHSO3, H20 or KMnO4/cold, dilute **1,2-diols syn-addition |
| PBr3 | OH to Br w/ inversion |
| SOCl2 | OH to Cl w/ inversion |
| TsCl/pyridine | OH to Cl w/o inversion |
| Alkene to cyclopropyl | CH2I2/Zn(Cu) |
| Alkene to cyclopropyl w/ 2 Cl's | CHCl3/tBuOK |
| Alcohol to asymmetrical ether | NaH, THF/other side of ether |
| Ozonolysis | O3, CH2Cl2, -78˚C/Zn, HoAC **alkene to carbonyl |
| Alkene to epoxides | mCPBA |
| Acid catalyzed ring openings | more substituted |
| Base catalyzed ring openings | less substituted |
| Bromination of alkanes | Br2, heat **alkene to leaving group; most stable radical! |
| Radical addition to alkenes | HBr, peroxide **anti-Markovnikov |
