Elemental Manganese - an overview ScienceDirect Topics

Alkylmanganese(II) derivatives can be obtained by oxidative addition to alkyl halides or sulfonates, or by transmetallation reactions. Elemental manganese is relatively unreactive and undergoes only oxidative addition to allylic halides. A reactive form of manganese, obtained by reduction of manganese halides with 2 equiv. of lithium metal and a catalytic quantity of naphthalene, is suitable ...

Manganese Mn (Element) - PubChem

Manganese minerals are widely distributed, with oxides, silicates, and carbonates being the most common. Large quantities of manganese nodules are found on the ocean floor and may become a source of manganese. These nodules contain about 24% manganese, together with many other elements in lesser abundance.

It's Elemental - The Element Manganese

Proposed to be an element by Carl Wilhelm Scheele in 1774, manganese was discovered by Johan Gottlieb Gahn, a Swedish chemist, by heating the mineral pyrolusite (MnO 2) in the presence of charcoal later that year.Today, most manganese is still obtained from pyrolusite, although it is usually burned in a furnace with powdered aluminum or is treated with sulfuric acid (H 2 SO 4) to form ...
