2 is also used as a pigment and as a precursor to other manganese compounds, such as KMnO 4. It is used as a reagent in organic synthesis, for example, for the oxidation of allylic alcohols. MnO 2 in the α polymorph can incorporate a variety of atoms (as well as water molecules) in the "tunnels" or "channels" between the manganese oxide octahedra.

For the oxidation of benzyl alcohols to benzaldehyde, this catalyst demonstrates near perfect performance, with conversion and selectivity figures of 99%. This means that the reaction uses up almost all of the starting material while almost completely avoiding unwanted side-products.
In situ ball milling of solid catalysts is a promising yet almost unexplored concept for boosting catalytic performance. The continuous preferential oxidation of CO (CO‐PROX) under in situ ball milling of Cu‐based catalysts such as Cu/Cr 2 O 3 is presented. At temperatures as low as −40 °C, considerable activity and more than 95 % selectivity were achieved.
An eco-friendly methodology for preparing carbamate N-protected α-amino acids is described using ball-milling technology. Some β-amino acids were also investigated in this study. This solvent-free methodology gave Boc-, Z-, and Fmoc-N-protected compounds in good to excellent yields with improved environmental impact compared to classical syntheses in solution. Different planetary ball mills ...
