Imide-catalyzed oxidation system: Sulfides to sulfoxides and sulfones

R1SR2 Imide(cat.), → Toulene or DME R 1SOR2 R1SO2R2 A new combination system, the oxidation of sulfides using aqueous NaOCl in the presence of a catalytic amount of imide under two-phase conditions, has been developed. The combination effectively converts various sulfides to the corresponding sulfoxides and sulfones. It was deduced that the imide could react with NaOCl to produce N-chloroimide, which would play roles of both the active oxidizing reagent and phase transfer catalyst.

PROCESS FOR THE PRODUCTION OF ORGANIC OXIDES

The present invention provides a method for producing an organic oxide, wherein a substrate is oxidized using hypohalous acid, hypohalous acid salt, chlorine, bromine or iodine in the presence of water and a catalytic amount of a compound represented by the following formula (I): R1-X1-NY-R2, wherein: X1 represents -CO- or -SO2-; Y represents a hydrogen atom, a potassium atom, a sodium atom, a chlorine atom, a bromine atom or an iodine atom; R1 represents a substituted or unsubstituted hydrocarbon group, -NYR3 group or -OR3 group (in the formulae, R3 represents a substituted or unsubstituted hydrocarbon group, and Y represents the same meaning as defined above); and R2 represents a hydrogen atom or -CO-R4 group (in the formula, R4 represents a substituted or unsubstituted hydrocarbon group, -NYR5 group or -OR5 group (in the formulae, R5 represents a substituted or unsubstituted hydrocarbon group, and Y represents the same meaning as defined above)); or R1 and R4 may bind to each other to form a further substituted or unsubstituted nitrogen-containing heterocyclic ring.

Solid-Phase Silica-Gel Catalyzed α-Halogenation of Alkyl Aryl Sulfoxides with N-Halosuccinimides

Alkyl aryl sulfoxides are readily halogenated by silica-gel supported N-halosuccinimides.The conversion of optically active alkyl 4-methylphenyl sulfoxides into 1-haloalkyl 4-methylphenyl sulfoxides is accompanied by inversion of configuration at the S-atom.The stereoselectivity of the solid-phase halogenation of alkyl aryl sulfoxides is much higher than that observrd for the halogenation in solution.
