Sulfinic Acids and Sulfinic Esters

Controlled-potential electrolysis of bulk solutions at a modified electrode: application to oxidations of cysteine, cystine, methionine, and thiocyanate

“…This procedure made use of a mobile phase of 7:3 95% ethanohwater (saturated atmosphere) and a stationary phase of Silica Gel-G. Elution times were 35-45 min. Low molecular weight sulfinic acids are air-oxidized (20). This reaction occurs during the development of the chromatogram and complicates the results.…”

Sulfinic Acids in Organic Synthesis: A Review of Recent Studies

“…However, less review was reported. In 1977, Oae and Kunieda [1a] provided an overview of sulfinic acids and sulfinic esters. A lot of methodologies about sulfinic acids have emerged in recent years.…”

Fenton's reagent in dimethyl sulphoxide: an unusual sulphonylating system. X-Ray crystallographic analysis of 4-N,N-dimethylamino-N,N-dimethane-sulphonylaniline

“…which the positive charge delocalized on the aromatic ring could explain the MeSO, -anion nuclear attack. Although this would fit the formation of (k), (&), (Sc), or (12), the recovery of (7) (sulphonylation at a non-conjugated position) and the methyl substitution in (&) seem harder to explain.…”
