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[1].

Application


  • High-oxidation-state 3d metal complexes: Explores the catalytic properties of manganese(IV) oxide within high-oxidation-state complexes for advanced organic synthesis, demonstrating its critical role in accelerating chemical reactions and enhancing yield efficiencies, beneficial for pharmaceutical and chemical industries (Cheng J et al., 2018).


  • Synthesis and properties of manganese complexes: Details the synthesis of new manganese complexes that demonstrate unique redox properties, useful for understanding electron transfer processes in various chemical and environmental contexts (Baffert C et al., 2002).
