Description

General description

Manganese(IV) oxide is an oxidizing reagent that can be used for the oxidation of propargylic alcohols, benzylic or heterocyclic alcohols, saturated alcohols, 1,2-diols, allylic alcohols to α, β-ethylenic aldehydes or ketones, and amines to aldehydes, imines, amides, and diazo compounds. It can also be used for the conversion of allylic alcohols to α, β-ethylenic esters or amides, hydration of nitriles to amides, dehydrogenation and aromatization reactions.
