Iodoarylation of arylacetylenes was performed using a simple reagent system composed of molecular iodine and [bis(benzoyloxy)iodo]benzene. Most arylacetylenes efficiently underwent the iodoarylation reaction with electron-rich arenes to give trans 1,1-diaryl-2-iodoethene adducts regio- and stereoselectively. As an exception, the iodoarylation of p-methoxyphenylacetylene resulted in a mixture of E- and Z-isomers of the corresponding product.

Iodoarylation of arylacetylenes with electron-rich arenes using a simple reagent system: I2 and PhI(OCOPh)2 proceeded regio- and stereoselectively to give trans adducts, 1,1-diaryl-2-iodoethenes, in good to high yields.
