DppfCuBH4: new reducing agents for the synthesis of ferrocene-functionalized metal nanoclusters

A novel type of functional reducing agent, dppfCuBH 4 , has been developed. Reduction of silver complexes by the reductant affords two ferrocene-functionalized clusters of [Ag 25 Cu 4 (dppf) 6 (3-F-PhCC) 12 Cl 6 ] 3+ and [Ag 4 (dppf) 5 Cl 2 ] 2+ in a facile way.
