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.
