The reaction of a substitutionally labile dipalladium(I) complex [Pd2(CH3CN)6][BF4]2 (1) with 1,3,5,7-cyclooctatetraene (COT) in acetonitrile afforded [Pd2(μ-η3:η3-C8H8)(CH3CN)4][BF4]2 (2). The reaction of 2 with COT in acetonitrile yielded [Pd2(μ-η3:η3-C16H16)(CH3CN)4][BF4]2 (4), where COT is dimerized via C–C bond formation. Complexes 2 and 4 were structurally characterized by X-ray diffraction analyses. In dichloromethane, COT isomerized to styrene at room temperature in the presence of catalytic amount of 1, 2, or 4.
Graphical abstractThe reaction of the reactive dipalladium(I) complex [Pd2(CH3CN)6][BF4]2 with cyclooctatetraene (COT) (1 equiv.) yields the mono-adduct [Pd2(μ-η3:η3-C8H8)(CH3CN)4][BF4]2. The mono-adduct reacts with COT to give the bicyclooctatrienyl complex [Pd2(μ-η3:η3-C16H16)(CH3CN)4][BF4]2. The products were structurally characterized by X-ray crystallographic analyses.Figure optionsDownload full-size imageDownload as PowerPoint slide
