《Photoredox-Catalyzed Functionalization of Alkenes with Thiourea Dioxide: Construction of Alkyl Sulfones or Sulfonamides》 was published in Chinese Journal of Chemistry in 2020. These research results belong to Li, Yuewen; Liu, Jin-Biao; He, Fu-Sheng; Wu, Jie. Formula: C7H6BrCl The article mentions the following:
Sulfonylation of alkenes through photoredox-catalyzed functionalization of alkenes with thiourea dioxide under visible-light irradiation is achieved. The reaction of alkenes, thiourea dioxide and electrophiles provides a green and efficient access to alkyl sulfones and sulfonamides. A broad reaction scope is presented with good functional group compatibility and excellent regioselectivity. A plausible mechanism involving a radical addition process with sulfur dioxide radical anion (SO2-) derived from the oxidation of sulfur dioxide anion (SO22-) is proposed, which is supported by fluorescence quenching experiments The results came from multiple reactions, including the reaction of 1-(Bromomethyl)-4-chlorobenzene(cas: 622-95-7Formula: C7H6BrCl)
1-(Bromomethyl)-4-chlorobenzene(cas: 622-95-7) is a useful reagent for the preparation of panicinotam derivatives for use as anti-inflammatory agents or immunomodulators.Formula: C7H6BrCl It can be synthesized by reacting 4-chlorobenzyl alcohol with bromodimethylsulfonium bromide (BDMS) It can also be synthesized by refluxing a mixture of 4-chlorobenzaldehyde, chlorotrimethylsilane, 1,1,3,3-tetramethyldisiloxane and lithium bromide.
