Ionita, P., Gilbert, B.C. and Chechik, V. (2005) Radical mechanism of a place-exchange reaction of Au nanoparticles. Angewandte Chemie International, 44 (24). pp. 3720-3722. ISSN 1433-7851
Spin-trapping experiments show the formation of sulfur-centered radicals during a ligand-exchange reaction between Ph3P-protected Au nanoparticles and alkanethiols in air (see picture). Oxidation of the alkanethiols by molecular O2 adsorbed on the nanoparticles is proposed as the key step. The feasibility of such a process is demonstrated by the Au-nanoparticle-catalyzed oxidation of BH4- and tBuOOH with air.
