Oxidation of Alcohols
Reaction type: Oxidation-Reduction
Cr OXIDATION OF ALCOHOLS
|The mechanism is not trivial,
so attention here is focussed on the actual oxidation step. Prior to this,
the alcohol reacts to form a chromate ester (shown). A base (here
a water molecule) abstracts a proton from the chromate ester, the C=O
forms and a Cr species leaves.
This demonstrates the importance of the carbinol H to this mechanism.
If you see Cr reagents, you are probably looking at an oxidation reaction.
Most likely the oxidation of an alcohol or an aldehyde
