ANTI-BACTERIAL AND ANTIFUNGAL
Title: IODONIUM SALTS
Inventor(s):G. Koser, S. Carman
Disclosure 48 U.S. Patent 4,513,137
Mono- or bis(iodonium salts) are produced in neutral organic solvents by the reaction of a [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.
Title:COMPOSITION AND A PROCESS FOR THE PREPARATION OF[HYDROXY (ORGANOSULFONYLOXY)IODO]ARENES AND THEIR USE INA REGIOSPECIFIC SYNTHESIS OF DIARYLIODONIUM SALTS

Disclosure 47 U.S. Patent 4,348,525 Disclosure 47-DIV U.S. Patent 4,826,635
[Hydroxy(organosulfonyloxy)iodo]arenes are synthesized in neutral organic solvents by the reaction of ring-substituted [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.
The various iodonium salts formed have a relatively high toxicity to a broad spectrum of bacteria, fungi, yeast and small RNA viruses.Moreover, such salts have a low toxicity to terrestrial plants.Applications include below and above ground agricultural uses, adhesives, cooling water, inks, plasticizers, resins, polymer materials, greases, detergents, soaps, shampoos, oils, paints, and the like to prevent mold and mildew.Additional uses include textiles, fabrics, paper, or other cellulosic products and further may be employed in the impregnation of wood, lumber, wallboard, plaster, and the like to prevent attack of bacteria organisms of rot, mold, mildew, and decay.
