(Chemical Equation Presented) Aliphatic thiolates were efficiently converted into the corresponding sulfenates by smooth oxidation with trans-(±)-2-tert-butyl-3-phenyloxaziridine at room temperature (five examples). Subsequent electrophilic quench with benzyl bromide led to sulfoxides (S-alkylation) in good to moderate yields. Application of the protocol to an aromatic substrate was also successful. This work represents the first valuable example of the use of this poorly active oxidizing agent in synthetic organic chemistry without the need for activating conditions.

Cobalt Schiff base complex catalyzed oxidation of secondary aromatic amines with t-butyl hydroperoxide resulted selectively in dehydrogenation to give the corresponding imines.Proposed mechanism involves electron transfer from the nitrogen atom in the substrate to t-butyloxyl or t-butylperoxyl radical produced in situ from a t-butylperoxocobalt(III) complex intermediate.
