HAPpy catalysts: Hydroxyapatite-supported gold nanoparticles efficiently catalyze the deoxygenation of amides, sulfoxides, and pyridine N-oxides, with silanes as reductants, to give the corresponding products with excellent turnover numbers (see graphic). Furthermore, this catalyst is easily recovered and reused without any loss of efficiency.
