Ne. Shevchenko et al., Synthetic potentialities of sulfonylsulfonium salts: a new approach to thepreparation of disulfonium dications, RUSS CHEM B, 49(8), 2000, pp. 1415-1420
A new efficient method for the generation of disulfonium dications whose su
bsequent hydrolysis selectively affords monosulfoxides was developed based
on the oxidation of bis-sulfides by trifluoromethanesulfonic anhydride.
