German chemist Hermann Kolbe discovered MSA between 1842 and 1845 and originally termed it methyl hyposulphuric acid. [4] [5] [6]The discovery stemmed from earlier work by Berzelius and Marcet in 1813, who treated carbon disulfide with moist chlorine and produced a compound they named "sulphite of chloride of carbon".
Methanesulfonyl chloride is mainly used to give methanesulfonates by its reaction with alcohols in the presence of a non-nucleophilic base. [8] In contrast to the formation of toluenesulfonates from alcohols and p-toluenesulfonyl chloride in the presence of pyridine, the formation of methanesulfonates is believed to proceed via a mechanism wherein methanesulfonyl chloride first undergoes an ...
Hydrogen peroxide is a typical oxidant—for example, with dimethyl sulfide (S(CH 3) 2): [9] S(CH 3) 2 + H 2 O 2 → OS(CH 3) 2 + H 2 O OS(CH 3) 2 + H 2 O 2 → O 2 S(CH 3) 2 + H 2 O. In analogy to their easy alkylation, sulfides bind to metals to form thioether complexes. Consequently, Lewis acids do not decompose thioethers as they do ethers ...
The C−S bond dissociation energy for thiomethane is 89 kcal/mol (370 kJ/mol) compared to methane's 100 kcal/mol (420 kJ/mol) and when hydrogen is replaced by a methyl group the energy decreases to 73 kcal/mol (305 kJ/mol). [5] The single carbon to oxygen bond is shorter than that of the C−C bond.
Dimethyl sulfone (DMSO 2) is an organosulfur compound with the formula (CH 3) 2 SO 2. It is also known by several other names including methyl sulfone and (especially in alternative medicine) methylsulfonylmethane (MSM). [4] This colorless solid features the sulfonyl functional group and is the simplest of the sulfones. It is relatively inert ...

Compounds that contain sulfur exhibit unique chemistry due to sulfur's ability to form more bonds than oxygen, its lighter analogue on the periodic table. Substitutive nomenclature (marked as prefix in table) is preferred over functional class nomenclature (marked as suffix in table) for sulfides, disulfides, sulfoxides and sulfones.
One-carbon compounds used as a carbon and energy source by methylotrophs are found throughout the ocean. These compounds include methane, methanol, methylated amines, methyl halides, and methylated sulfur compounds, such as dimethylsulfide (DMS) and dimethylsulfoxide . [30]
