The palladium-catalyzed amidation of electron-deficient aryl chlorides proceeds readily in the presence of low CO pressures and a slight excess of an iodide salt. The rates of amidation are accelerated over those without added salt, and iodide is preferred over
Reductive dehalogenation versus substitution in the polyetherification of 4, 4'-dihalodiphenyl sulfones with bisphenolates.
