title: Atomic-scale insight into the formation, mobility and reaction of Ullmann coupling intermediates.
abstract: The Ullmann reaction of bromobenzene, the simplest coupling reagent, to form biphenyl on a Cu surface proceeds via a highly mobile organometallic intermediate in which two phenyl groups extract and bind a single surface Cu atom.
