Reagents Flashcards
1
Q
To oxidize Primary Alcohols
A
•PDC/PCC in CH2Cl
-primary OH–>aldehydes (H is lost)
- Jones(CrO3, H2SO4) or Na2Cr2O7
- KMnO4, NaOH,
2
Q
Oxidation of Secondary Alcohols
A
PDC/PCC in CH2Cl2
Jones or Na2Cr2O7
-secondary OH–>ketone (no more H’s to give up)
3
Q
Oxidation of Tertiary Alcohols
A
Tertiary alcohols do not undergo oxidation!!
4
Q
Oxidative Cleavage Rxns
A
•cold, dilute KMnO4 (tends to oxidize everything) -adds to Alkene with syn addition •OsO4(expensive and toxic) •HIO4(periodic acid) -forms aldehydes
5
Q
Ozonolysis
A
O3 and Zn, HCl
Produces carbonyl groups
6
Q
Epoxidation
A
Forms ethers
Occurs steep specifically with syn addition and that stereochem is carried into the epoxide
m-Chloroperbenzoic acid (mCPBA) is reagent
