Alkene Reactions Flashcards
1
Q
Addition of HX
A
- Markovnikov’s rule
2
Q
Hydration
A
-Alcohols
- 3 methods:
1. Brute force
2. Oxymercuration
3. Hydroboration
3
Q
Brute force hydration
A
- Acid catalyst (50% H2SO4 and 50% H2O)
- Problems: 1. Highly acidic conditions
2. High temp.
4
Q
Oxymercuration
A
2 steps:
1. Treatment with mercuric acetate
2. Treatment with sodium borohydride
- Markovnikov addition
5
Q
Hydroboration
A
- Anti markovnikov
- Syn addition (H and OH on same side of ring)
6
Q
Hydrogenation
A
- H2 gas
-Metal catalyst = Pt/C, Pd/C, PtO2 (Adams reagent)
7
Q
Oxidation
A
-2 types:
1. Ozonolysis
2. Oxidative cleavage
8
Q
Ozonolysis
A
- Aldehydes and ketones are formed
- 2 step reaction
1. O3, CH2Cl2
2. Zn/H+ or (CH3)2S
9
Q
Oxidative Cleavage
A
- KMnO4
- Forms CO2 when terminal alkene is used
