General Procedure for the Sulfoxidation.The catalyst precursor
2 (6.3 mg,0.02 mmol) was dissolved in [BMIm]PF6 (0.5 mL)
and methanol (3.2 mL) in a 20 mL vial.The sulfide (1 mmol) was
then added followed by hydrogen peroxide (30% in water) (170
íL).The reactions were stirred for the given time (the reactions
were followed by TLC) after which the methanol was removed
and the residual ionic liquid was extracted with diethyl ether (3 \2 15 mL).The combined ether layers were treated with sodium
dithionite and washed with water (3 \2 10 mL).The ether phase
was dried over Na2SO4,filtered,and concentrated in vacuo.The
products were purified by conventional or Biotage flash chromatography.
p-Tolyl Methyl Sulfoxide (8b).Isolated yield after 1 h of
reaction time,78%.The NMR data were in accordance with those
previously reported.4 The conversions (Figure 3) were determined
by GC analysis of the reaction mixture:tR(p-tolyl methyl sulfide)
) 12.7 min; tR(p-tolyl methyl sulfoxide) ) 17.2 min.
General Procedure for the Recycling of the Ionic Liquid-
Catalyst System.The catalyst precursor 2 (6.3 mg,0.02 mmol)
was dissolved in [BMIm]PF6 (0.5 mL) and methanol (3.2 mL) in
a 20 mL vial.The sulfide (1 mmol) was then added followed by
hydrogen peroxide (170 íL).The reaction was stirred for the given time (the reaction was followed by TLC) after which the methanol
was removed and the residual ionic liquid was extracted with diethyl
ether (3 \2 15 mL).The combined ether layers were treated with
sodium dithionite and washed with water (10 mL).The water phase
was back extracted with diethyl ether (3 \2 10 mL).The combined
ether phases were dried over Na2SO4,filtered,and concentrated in
vacuo.The products were isolated by flash chromatography.The
ionic liquid phase was reused after evaporation of the remaining
diethyl ether.Sulfide (1 mmol) and H2O2 (1.5 equiv) were added
after addition of methanol (3.2 mL).
