  • Antimicrobial diaryl iodonium compositions and method
    Patent number: 8053478
    Abstract: Disclosed are diaryl iodonium compositions with antimicrobial activity and low toxicity to plants and mammals. The present diaryl iodonium compositions include a tri-substituted aryl group and a heteroaryl group which produce substantially no chlorobenzene and/or 1,2-dichlorobenzene when applied to microbes.
    Type: Grant

  • Process for the production of diaryl iodonium compounds
    Patent number: 7052593
    Abstract: The present invention provides an electrochemical method for producing diaryl iodonium compounds wherein application of an electric current to an electrochemical cell containing a reaction mixture composed of a solvent, an iodoaryl compound and an electrolyte forms an oxidizing agent in situ. In this first step, the oxidizing agent is subsequently converted into a stable oxidized iodoaryl intermediate, typically an iodosyl compound. The electric potential is removed and in a second step a target aryl compound is introduced to the reaction mixture to react with the oxidized iodoaryl intermediate to form a diaryl iodonium compound.
