Giant cluster catalysis: possible intermediacy of nitrene and carbene species

Coordinated carbene and nitrene species were suggested as the key intermedi ates in hydrogen-transfer reduction of multiple bonds and reduction of nitr oaromatics by CO catalysed with giant Pd-561 clusters as well as in the rea ction of Pd (I) carbonylacetate cluster with nitrosobenzene. In the last re action, a palladium complex with phenyl-o-nitrosophenylamide was obtained w hose structure gives evidence for the intermediacy of nitrene ligands in Pd -catalysed reactions.
