Sulfur–Sulfur Bond Construction
Topics in Current Chemistry, 2018Disulfide, as a common structural motif, has been frequently used in pharmaceuticals, nature products, and chemical biology. This chapter focuses on the methodologies that were reported recently for the synthesis of disulfide-containing compounds with particular emphasis on the synthesis of unsymmetrical disulfides.

Sulfur is one of the few elements that is found in its elemental form in nature. Typical sulfur deposits occur in sedimentary limestone/gypsum formations, in limestone/anhydrite formations associated with salt domes, or in volcanic rock [1]. A yellow solid at room temperature, sulfur becomes progressively lighter in color at lower temperatures and is ...

Sulfur Metabolism in Phototrophic Sulfur Bacteria
2008Phototrophic sulfur bacteria are characterized by oxidizing various inorganic sulfur compounds for use as electron donors in carbon dioxide fixation during anoxygenic photosynthetic growth. These bacteria are divided into the purple sulfur bacteria (PSB) and the green sulfur bacteria (GSB). They utilize various combinations of sulfide, elemental sulfur,

Sulfur is one of the few elements that is found in its elemental form in nature. Typical sulfur deposits occur in sedimentary limestone/ gypsum formations, in limestone/anhydrite formations associated with salt domes, or in volcanic rock.4 A yellow solid at normal temperatures, sulfur becomes progressively lighter in color at lower temperatures and is ...

Properties of Sulfur‐Sulfur Bonds
Angewandte Chemie International Edition in English, 1975AbstractSS bonds are extraordinarily flexible and have properties that are observed only on isolated occasions for other homonuclear bonds: the bond lengths very between 1.8 and 3.0Å, the bond angles between 90 and 180° and the dihedral angles between 0 and 180°; the bond energies amount to up to 430 kJ/mol.

Sulfur is unusual in that it is a mineral that may be taken into the body in both inorganic and organic combinations. It has been available within the environment throughout the development of lifeforms and as such has become integrated into virtually every aspect of biochemical function.

Nickel mediated sulfur–selenium and sulfur–sulfur bond formation
Chemical Communications, 1999Electrophilic addition of the PhSeCl to a nickel dithiolate yields S,S′-bis(phenylselenenyl-N,N′-bis(mercaptoethyl)-1,5-diazacyclooctane nickel(II) dichloride and a dimeric, intermolecular bis-disulfide which results from ligand oxidation.

Derivatives of sulfuric and sulfurous acids
1971Sulfuric acid was used previously as a herbicide; at present it is used for the desiccation of potato plant tops for the purpose of mechanizing the harvesting. However, because treatment with sulfuric acid greatly increases the acidity of the soil and requires subsequent liming, its scale of use is rapidly declining.

The Action of Sulfur Trioxide on Elemental Sulfur
Zeitschrift für anorganische und allgemeine Chemie, 1971AbstractThe reaction between SO3 and elemental sulfur to form SO2 proceeds with maximum rate at 70°C, The decrease in rate at higher temperature is supposed to be due to the dissolution of SO3 in molten sulfur then its decomposition according to: SO3 → SO2 + 1/2 O2.
