Article abstract of DOI:10.1016/S0040-4039(00)73979-7

The oxaziridinium salt 1 derived from dihydroisoquinolin is an oxygen transfer reagent to thioethers leading either to sulfoxides with a good selectivity when used in stoichiometric amounts, or to sulfones when used in excess (2 eq.).These reactions may be performed with an oxaziridinium salt prepared in situ by the reaction of oxone in alcaline medium with the corresponding iminium salt 2 in catalytic amount.
