  • Iodones and methods for antimicrobial use
    Patent number: 5106407
    Abstract: The present invention discloses the antimicrobial utility of certain iodonium ylide compounds. The particular iodonium ylide compounds are phenyl iodonium ylides having an ortho substituent that stabilizes the positive charge on the polyvalent iodine by a nonbonded electrostatic interaction. The polyvalent iodine is further stabilized by a cyclic 1,3-dicarbonyl anion.
    Type: Grant

  • Composition and a process for the preparation of (hydroxy (organosulfonyloxy)iodo)arenes and their use in a regiospecific synthesis of diaryliodonium salts
    Patent number: 4826635
    Abstract: [Hydroxy(organosulfonyloxy)iodo]arenes are synthesized in neutral organic solvents by the reaction of ring-subsituted [hydroxy(organosulfonyloxy)iodo]benzenes with iodoarenes via ligand transfer. The produced compounds are reacted with (triorganosilyl) arenes or (trihalosilyl)arenes in neutral organic solvents to produce diaryliodonium salts. The diaryliodonium salt synthesis proceeds in regiospecific fashion, aryliodination occurring at the point of attachment of the silicon atom in the silylarenes.

  • Iodonium salts
    Patent number: 4513137
    Abstract: Mono- or bis(iodonium salts) are produced in neutral organic solvents by the reaction of an [hydroxy (organosulfonyloxy)iodo]arene with a bis(triorganosilyl)arene, a bis(trihalosilyl)arene, or with a mono- or bis(triorganosilyl)heterocyclic compound, or a mono- or bis(trihalosilyl)heterocyclic. The iodonium salts are made under conditions of regiospecific control.
