Usage

General Description

Chloromethyl Phenyl Sulfone is a chemical compound denoted by the molecular formula C7H7ClO2S. As part of the organosulfur class of compounds, characterized by their sulfur-containing carbon-to-hydrogen bonds, it possesses unique chemical reactivity; this is because sulfur has a diverse range of oxidation states and can form stable compounds with all elements except the noble gases. The presence of both chloromethyl and phenyl groups in the chemical structure indicates that this compound is possibly utilized in various chemical synthesis processes as a reactive intermediate or precursor molecule. However, as with any chemical, its potential human health impacts need to be evaluated and any exposure mitigated appropriately, especially when used in an industrial context. Specific information pertaining to its physical and chemical properties, toxicity, regulatory requirements, and practical applications remain to be investigated.

Synthetic Studies on the Preparation of Alanyl Epoxysulfones as Cathepsin Cysteine Protease Electrophilic Traps

A Darzens reaction between tert-butoxycarbonyl alaninal and chloromethyl phenyl sulfone afforded chlorohydrins, which were converted into epoxysulfones by reaction with sodium tert-butoxide. Epoxysulfone 10 and chloroketone 14 derived from chlorohydrins by oxidation proved to be inhibitors of cathepsins H, S, and C as determined by competitive activity-based protein profiling.

Selectivity switch in the aerobic oxygenation of sulfides photocatalysed by visible-light-responsive decavanadate

Nanometre-sized metal oxides are promising species for the development of visible-light-responsive photocatalysts for the selective transformation of organic functional groups. In this article, we report that decavanadate ([V10O28]6-, V10) behaved as an efficient visible-light-responsive photocatalyst in the product-selective oxygenation of sulfides achieved using O2 (1 atm) as the green oxidant. In particular, we revealed that visible-light-responsive photocatalysis of V10 showed remarkable activity for the oxygenation of structurally diverse sulfides to form the corresponding sulfones using O2 in methyl ethyl ketone (MEK). Furthermore, by simply adding water to the reaction mixture, the product selectivity of sulfide oxygenation can be significantly switched toward the production of sulfoxides, without concomitant loss of photocatalytic activity. Based on experimental evidence, we inferred the following mechanistic steps for this photocatalytic system: the aerobic oxygenation of sulfides to form the corresponding sulfoxides initiated by a visible-light-induced photoredox reaction of V10. As for the formation of sulfones, MEK-derived peroxide species as the co-catalysts are probably involved in the oxygenation of sulfoxides to sulfones. The selectivity switch of the V10-photocatalysed reaction brought about by water addition is most likely achieved by suppressing the formation of MEK-derived peroxide species. This journal is

Controlled α-mono- and α,α-di-halogenation of alkyl sulfones using reagent-solvent halogen bonding

The direct and selective α-mono-bromination of alkyl sulfones was achieved through base-mediated electrophilic halogenation. The appropriate combination of solvent and electrophilic bromine source was found to be critical to control the nature of the products formed, where reagent-solvent halogen bonding is proposed to control the selectivity via alteration of the effective size of the electrophilic bromine source. Conversely, the α,α-di-brominated sulfones were selectively obtained in good yields following polyhalogenation followed by selective de-halogenation during workup. Both procedures can be applied on gram scale, and the mono-halogenation was successfully extended to the fully selective α-chlorination, α-iodination and α-fluorination of alkyl sulfones.
