title: Amidine Production by the Addition of NH3to Nitrile(s) Bound to and Activated by the Lewis Acidic [Re6(μ3-Se)8]2+Cluster Core.
abstract: Acetonitrile bound to and activated by the Lewis acidic [Re6(μ3-Se)8]2+cluster core was transformed into acetamidine in quantitative yield using NH3as the nucleophile at room temperature. The amidine ligand was removed by treating the cluster-acetamidine complexes with trifluoroacetic acid in CH3CN, affording amidinium trifluoroacetate and the starting acetonitrile complexes.
