Abstract

Photolysis of alkynyl (phenyl) iodonium salts in CH 2 Cl 2 resulted in major formation of iodobenzene, while the photolysis in EtOH, Et 2 O, or THF gave iodoalkynes as the main product. In addition to the organic products, acids were generated almost quantitatively by the photolysis and initiated polymerization of styrene.
