Aldehydes & Ketones Aldehyde R-C=O H Ketone R-C=O R Synthesis: Oxidation: 1° alcohol → aldehyde 2° alcohol → ketone a) iPr-CH2OH (1° alcohol) → PCC or PDC or Swern or DMP or TEMPO → iPr-CHO (aldehyde) b) iPr-CH(CH3)OH (2° alcohol) → "Same as above" → iPr-C(CH3)=O (ketone) Oxidation of Alkenes: a) Ozonolysis rxn: Example 1: CH3 H-C=C-H + O3, DCM → H-C=O + O=C-H Example 2: H-C=C-H + O3, DCM → H-C=O + O=C-H Example 3: CH3 | CH3-C-CH2-CH2-CH3 | CH3 O3, DCM H2O Products: CH3 | CH3-C=O + HO-CH2-CH2-CH3 Example 4: CH3 | CH3-C=C-H O3, DCM H2O Products: CH3 | CH3-C=O + CO2
