SULFINES IN THE OXIDATIONS OF 1,2-DITHIOLE-3-THIONES
Tamagaki, Seizo,Hotta, Kazuhiko,Kozuka, Seizi
, p. 619 - 620 (1980)
The oxidation of 1,2-dithiole-3-thiones with MCPBA or NaIO4 gives the sulfines in good yield, while the reactions with O2l, O3, NaOCl, and BPO produce 1,2-dithiole-3-ones which are formed via the sulfines as transient intermediates.
