A novel dry route to ortho-functionalized triarylbismuthanes that are difficult to access by conventional wet routes

Abstract

When an aryl iodide bearing an electron-withdrawing group at the ortho position was milled together with bismuth shots and calcite grains in the presence of Cu powder and CuI using a laboratory ball mill, the corresponding ortho-functionalized triarylbismuthane was obtained in moderate to good yield.
