Summary
One of the main advantages of doing green chemistry is that it can often be done on the bench top without the need of a fume-hood. In this experiment water and ethanol are the only solvents used for both the reaction and purification steps and oxone is a safe oxidant whose only by-product is potassium sulfate.
The oxidation of aromatic aldehydes using oxone allows instructors to discuss green chemistry, oxidation reactions and recrystallizations. Other topics include the use of melting points and NMR for characterization.
Included are supplemental materials which provide instructor notes, student lab procedure, a list of necessary materials, spectroscopic data and the proposed reaction mechanism.
