Manganese(II) sulfide is a chemical compound of manganese and sulfur. It occurs in nature as the mineral alabandite (isometric), rambergite (hexagonal), and recently found browneite (isometric, with sphalerite-type structure, extremely rare, known only from a meteorite).
Manganese(II) sulfate usually refers to the inorganic compound with the formula MnSO 4 ·H 2 O. This pale pink deliquescent solid is a commercially significant manganese(II) salt. Approximately 260,000 tonnes of manganese(II) sulfate were produced worldwide in 2005. It is the precursor to manganese metal and many other chemical compounds.
Organomanganese chemistry is the chemistry of organometallic compounds containing a carbon to manganese chemical bond.In a 2009 review, Cahiez et al. argued that as manganese is cheap and benign (only iron performs better in these aspects), organomanganese compounds have potential as chemical reagents, although currently they are not widely used as such despite extensive research.
Ore fluids debouched onto the seafloor and pooled in a second-order sub-basin's depocentre, precipitating a stratiform massive sulfide layer from 3 to 8 m thick, with exhalative chert, manganese and probable K-bearing hydrothermal clays. The central area of the exhalitive massive sulfides lying above the feeder zone became progressively ...
Manganese-mediated couplings have been used for the synthesis of hydrocarbon natural products, such as pheromones. A synthesis of queen bee pheromone uses the intermolecular coupling of acetone and an ω-alkenyl acetate en route to the target. [18] (11) Lactonization is a key step in the synthesis of tomato pinworm sex pheromone.
Sulfur can also serve as both an electron donor and electron acceptor by microorganisms is disproportionation reactions. For example, Acidianus ambivalens uses sulfur oxygenase reductase (SOR) to convert elemental sulfur to sulfate, thiosulfate, and hydrogen sulfide through disproportionation. [16]
Reactions of oxidation of sulfide to sulfate and elemental sulfur (incorrectly balanced). The electrons (e −) liberated from these oxidation reactions, which release chemical energy, are then used to fix carbon into organic molecules. The elements that become oxidized are shown in pink, those that become reduced in blue, and the electrons in ...
Manganese disulfide or Manganese(IV) Sulfide is a sulfide compound of manganese. It occurs naturally in the mineral hauerite. [2] References
