The reactions of ketones 1a -o, nitromethane 2, and a stoichiometric amount of piperidine 3a or ethylenediamine 3b in the presence of mercaptan 6a in THF or CH 3 CN solution give high yields of b-nitrosulfides 7a -o. The latter can be oxidized by 8a (m-CPBA or m-CPBA/AcOH) at 08C, 8b (H 2 O 2 /AcOH)
