Synthesis Of Alkynyliodonium Salts: Preparation Of Phenyl(Phenylethynyl)Iodonium Trifluoroacetate

Alkynyliodonium salts are highly versatile reactive intermediates and as such, have been used in a number of cycloaddition reactions including 1,3-dipolar cycloadditions with nitrile-oxides, diazoketones and azides as well as Diels-Alder chemistry. This article discusses the preparation procedure of phenyl(phenylethynyl)iodonium trifluoroacetate.
