All the substrates used in this study were purchased from Aldrich
and used as received. The solvents used were purchased from
1
Ranchem, India and purified using standard methods. H and 13C
spectra were recorded with a Bruker Avance 400 instrument. Chem-
ical shifts were referenced to residual solvent resonances and are re-
ported as parts per million relative to SiMe4. CDCl3 was used for
NMR spectral measurements. GC-MS were recorded using Jeol
JMS GC-Mate II instrument. HPLC analysis was done with Waters
HPLC instrument fitted with Waters 515 pump and Waters 2487
dual-wavelength absorbance detector.

Sulfoxides; Typical Procedure
To a stirred soln of AgNO3 (8.05 mg, 0.05 mmol) and sulfide/disul-
fide (1 mmol) in MeCN (2.5 mL) was added 70% aq t-BuOOH
(0.64 mL, 5 mmol). The mixture was heated to reflux and the
progress was monitored by TLC until all sulfide/disulfide was
found consumed. After completion, MeCN was evaporated and the
crude mixture was washed with NaHCO3 and extracted with
EtOAc. The EtOAc was evaporated followed by flash column puri-
fication to obtain the pure sulfoxides. The product was character-
ized using 1H, 13C NMR spectroscopy, ESI-MS and IR
spectroscopy. The data were found to be in accord with the literature
(see Supporting Information).
