22
Q
cyclopropanation
A
23
Q
HCL
A
HX
- H less sub and Cl most sub =
24
Q
HBr/ROOR
A
antimark
- not other roor
25
HOH
- Hydration
- OH on most sub
- look for methyl shift
26
is rearrangement possible on oxymercuration?
no
27
Hg(OAc)2
end with OH, H
- oxymercuration
28
BH2, -THF
H2O2, -OH
anti
- Gives H and OH
29
Br2, Cl2, I2
cis
- anti addition if trans
30
CCl4
solvent
31
Cl2/ H20
gives 1 Cl and OH
32
OH and X
Cl2/H20
- OH on most sub
- halohydrins
33
catalytic hydrogenation of alkenes
use H2 with Ni, Pd, or Pt
- gives wedge or dash
34
both catalytic hydrogenation wedges
syn
35
epoxidation
- CO3H
- opens ring if acidic
- line angle = triangle O
- ring = 2 OH
36
syn dihydroxylation
- gives OH on same side
- OsO4, H2O2
- KMnO4, OH- cold and diluted
37
oxidative cleavage
- KMnO4 warm and conc
- break and replace with = O
38
Warm and Conc
O = and OH
39
O3 in -78
CH3)2S
O = H and H
- O leaves
