the solvent free route for the synthesis of diaryl sulfoxides from arenes and thionyl chloride in the presence of lewis acids such as aluminum chloride and ferric chloride on silica gel are described.
[Cp*Rh(bpy)(H2O)]2+ was applied as a flavin regenerating reagent in BVMO catalyzed oxidations of organic sulfides to chiral sulfoxides.
An efficient isocyanide-based synthesis of S-thiocarbamates was discovered and thoroughly investigated. The new reaction protocol is a one-pot procedure allows the direct conversion N-formamides into thiocarbamates by initial dehydration with p-toluene sulfonyl chloride to respective isocyanide subsequent addition sulfoxide component. Contrary recent literature, which also uses isocyanides as s...
An efficient and practical catalytic method for the aerobic oxidative transformation of sulfides into sulfoxides, and thiols into disulfides with formic acid/TEA in the presence of a new, readily available, and stable flavin catalyst 5d is described.
We present a convenient and efficient deoxygention method for the syntheses of disulfides thioethers. The reaction involves an iodide-catalyzed reduction methyl sulfinates or sulfoxides, respectively, employing formic acid...
The bond dissociation enthalpies (BDEs) of sulfur and selenium ylides have been estimated by applying MP2/6-311++G(3df,2p)//MP2/6-31G(d,p), G3, and other computational methods. Computed sulfoxide bond enthalpies were compared to experimental results to ensure the reliability of the computational methods before extending to related compounds. The examined ylides include the following: sulfoxides...
