Abstract:Herein we utilized, for the first time, 2-iodoxybenzoate along with scandium triflate as a specific oxidant for PhthNH2 to create sulfoximines. This method efficiently effects imination of aryl, benzyl, cyclic and alkyl substituted S?O bonds with good to excellent yields. In addition, sterically encumbered sulfoxides have been studied and found that the present protocol is the worthy choice. This facile method does not require either inert atmosphere or anhydrous solvents.
Keywords:Hypervalent iodine  IBX  N-aminophthalimide  scandium triflate  sulfoximination
