Ce Cerium(IV) ammonium nitrate
Mechanism + Description
Mechanism unclear –Ce(IV) is a one electron oxidant, so maybe a radical process
(NH4)2Ce(NO3)6 supported on modified silica can be used as a catalyst for the oxidation of alcohols to aldehydes and ketones. A terminal oxidant is used- typically sodium bromate. Over-oxidation can be an issue.
Cerium is of low toxicity but damaging to aquatic organisms. Ce is rated as at high probability of depletion.
Tetrahedron Letters, 2003, 44(4), 769-771 The oxidation of a range of alcohols to ketones or carboxylic acids proceeds in good yield using catalytic quantities of cerium(IV) phosphonate modified silica and sodium bromate as the re-oxidant.
