Resumen:
Complexes of FeBr3 with -cyclodextrin (-CD-Fe), hydroxypropyl--cyclodextrin (HPCD-Fe) and -cyclodextrin (-CD-Fe) were
prepared from the interaction of the salt dissolved in CH2Cl2 and solid cyclodextrins, and analyzed by differential scanning calorimetry
(DSC), thermogravimetric analysis (TGA), infrared spectroscopy (IR) and elemental analysis. These complexes were used as catalysts in the
oxidation reactions of sulfides to sulfoxides giving good yields and a high chemoselectivity. The solid complexes can be used several times
and in the case of the -CD-Fe complex after five cycles the yield decreased only 5% (from 85 to 80%).
