Transition-metal complexes with one or more gold atoms need help to catalyze cross-couplings such as the Sonogashira reaction, but gold nanoparticles can go it alone, according to work from a team led by Avelino Corma of Spain’s Polytechnic University of Valencia (Chem. Commun., DOI: 10.1039/c0cc04564k). Last year, Antonio M. Echavarren of Spain’s Institute of Chemical Research of Catalonia and coworkers questioned several groups’ work, including Corma’s, on gold complexes . . .
