As is clear from the recycling experiments,the catalyst stays
in the ionic liquid and no detectable leaching of the catalyst
takes place.The system is equally active in the seventh run as
in the first run.It is important to note that the catalyst system
could be stored in the freezer for days between the runs with
neither decomposition nor loss of activity of the catalyst.This
is noteworthy since the flavin catalysts are usually sensitive
toward autooxidative degradation in solution.
In conclusion,we have developed a mild and robust catalytic
system for sulfoxidation.The combination of an electrondeficient
flavin catalyst with the use of an ionic liquid as medium
leads to an efficient and stable system.We have shown that a
variety of sulfides can be selectively oxidized to sulfoxides in
good yields.It was demonstrated that the catalyst in the ionic
liquid can be recycled up to seven times.The selectivity and
yield did not decrease on recycling,and the only product
obtained was the desired sulfoxide.The efficient immobilization
of flavin 2 is most likely due to it being present as its zwitterion
form and therefore it is not extracted by ether.
