Selective synthesis of sulfoxides and sulfonesviacontrollable oxidation of sulfides withN-fluorobenzenesulfonimide

A practical and mild method for the switchable synthesis of sulfoxides or sulfonesviaselective oxidation of sulfides using cheapN-fluorobenzenesulfonimide (NFSI) as the oxidant has been developed. These highly chemoselective transformations were simply achieved by varying the NFSI loading with H2O as the green solvent and oxygen source without any additives. The good functional group tolerance makes the strategy valuable.

PROCESS FOR PRODUCING 4,4'-DICHLORODIPHENYL SULFONE

The invention relates to a process for producing 4,4'-dichlorodiphenyl sulfone comprising reacting a solution comprising 4,4'-dichlorodiphenyl sulfoxide and at least one linear C6-C10 carboxylic acid as solvent with an oxidizing agent to obtain a crude reaction product comprising 4,4'- dichlorodiphenyl sulfone, wherein the concentration of water in the reaction mixture is kept below 5 wt%, the process comprising: (a) adding 0.9 to 1.05 mol oxidizing agent per mol 4,4'-dichlorodiphenyl sulfoxide uniformly distributed to the solution at a temperature in the range from 80 to 105 °C over a period from 1.5 to 5 h in a first step to obtain the reaction mixture; (b) agitating the reaction mixture after completion of the first step at the temperature of the first step for 5 to 30 min without adding oxidizing agent; (c) adding 0.05 to 0.2 mol oxidizing agent per mol 4,4'-dichlorodiphenyl sulfoxide to the reaction mixture at a temperature in the range from 80 to 105 °C over a period of less than 40 min in a second step; (d) agitating the reaction mixture after completion of the second step at the temperature of the second step for 10 to 30 min without adding oxidizing agent, (e) heating the reaction mixture to a temperature in the range from 95 to 110°C and hold this temperature for 10 to 90 min to obtain a crude reaction product comprising 4,4'- dichlorodiphenyl sulfone.
