Synergistic Effect in Bimetallic Ni–Al Clusters. Application to Efficient Catalytic Reductive Dehalogenation of Polychlorinated Arenes

Subnanometric Ni–Al clusters, in situ prepared by reduction of equimolar amounts of Ni(OAc)2 and Al(Acac)3 induced by alkoxide activated sodium hydride, exhibit a high catalytic activity for efficient reductive dehalogenation of aliphatic and aromatic halides and polychlorinated arenes.
