Development of Imino-λ3-iodanes with Improved Reactivity for Metal-Free [2+2+1] Cycloaddition-Type Reactions
Aiming at the enhancement of electrophilicity of imino-λ3-iodanes, we have developed (tosylimino)pentafluorophenyl-λ3-iodane, which shows superior reactivity compared to the commonly used (tosylimino)phenyl-λ3-iodane in the [2+2+1]-type synthesis of imidazoles. (Figure presented.).

Improving alkynyl(aryl)iodonium salts: 2-anisyl as a superior aryl group
The majority of alkynyl(aryl)iodonium salts reported in the literature are derived from iodobenzene. This article describes the effects of varying this iodoarene building block on the synthesis, reactivity and stability of these salts. Two procedures to synthesize a variety of known and novel alkynyl(aryl)iodonium tosylates directly from the iodoarene are reported. In the reactions of these salts, those derived from 2-iodoanisole gave superior results than the others tested in every reaction. Isothermal microcalorimetry indicated that these novel salts were significantly more stable and less prone to decomposition than all of the other derivatives. This journal is the Partner Organisations 2014.

Iodones and methods for antimicrobial use
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
