Usage

General Description

[(ethylsulfonyl)methyl]benzene, also known as toluene sulfonylmethyl methyl sulfone, is a chemical compound with the molecular formula C9H12O2S2. It is a clear, colorless liquid with a low boiling point and a characteristic odor. [(ethylsulfonyl)methyl]benzene is commonly used in the production of pharmaceuticals, insecticides, and other organic chemicals. Additionally, it can be used as a solvent, an intermediate in organic synthesis, and a cross-linking agent in polymer chemistry. It is considered to be a hazardous chemical and should be handled with care, as it is a strong irritant to the eyes, skin, and respiratory system.

Ceramic boron carbonitrides for unlocking organic halides with visible light

Photochemistry provides a sustainable pathway for organic transformations by inducing radical intermediates from substrates through electron transfer process. However, progress is limited by heterogeneous photocatalysts that are required to be efficient, stable, and inexpensive for long-term operation with easy recyclability and product separation. Here, we report that boron carbonitride (BCN) ceramics are such a system and can reduce organic halides, including (het)aryl and alkyl halides, with visible light irradiation. Cross-coupling of halides to afford new C-H, C-C, and C-S bonds can proceed at ambient reaction conditions. Hydrogen, (het)aryl, and sulfonyl groups were introduced into the arenes and heteroarenes at the designed positions by means of mesolytic C-X (carbon-halogen) bond cleavage in the absence of any metal-based catalysts or ligands. BCN can be used not only for half reactions, like reduction reactions with a sacrificial agent, but also redox reactions through oxidative and reductive interfacial electron transfer. The BCN photocatalyst shows tolerance to different substituents and conserved activity after five recycles. The apparent metal-free system opens new opportunities for a wide range of organic catalysts using light energy and sustainable materials, which are metal-free, inexpensive and stable.

Cyanide-Mediated Synthesis of Sulfones and Sulfonamides from Vinyl Sulfones

We report a facile synthesis of sulfones, β-keto sulfones, and sulfonamides from vinyl sulfones via an addition-elimination sequence where in situ generation of nucleophilic sulfinate ion is mediated by cyanide. The use vinyl sulfones renders high selectivity for S -alkylation to produce sulfones in high yields. In the presence of N -bromosuccinimide, primary and secondary amines underwent sulfonamide formation. A preliminary mechanistic study showed the formation of acrylonitrile as an innocent byproduct, without interfering with the desired reaction pathway while generating a sulfinate nucleophile.

Selective oxidation of sulfides to sulfoxides/sulfones by 30% hydrogen peroxide

A selective and efficient procedure for the oxidation of various sulfides with sodium tungstate dihydrate with 30% hydrogen peroxide in the presence of trioctylmethylammonium dihydrogen phosphate, respectively, to the corresponding sulfoxides and sulfones is reported. The oxidation reaction is carried out at -5 to 0 °C in the presence of hydroxypropyl -β cyclodextrins for sulfoxides or at 50-60 °C for sulfones. The mild reaction conditions, easy workup, and good yields of the products are the major advantages of this method. Copyright Taylor and Francis Group, LLC 2012.
