  Photochemical Modification of Carbene-Based Metallacycles: A Facile Route to Polycarbene Complexes and Their Derivatives

  摘要：

  The modification of dinuclear silver metallcycles via photochemical [2 + 2] cycloaddition is described. Reaction of benzimidazole with trans-4,4'-dibromostilbene gives trans-4,4'-bis(1H-benzo[d]imidazolyl)stilbene (L), which after subsequent dialkylation with alkyl bromides and anion exchange yields the corresponding dibenzimidazolium salts H-2-1(PF6)(2) and H-2-2(PF6)(2). The dibenzimidazolium salts react with Ag2O to give the dinudear silver(I) tetracarbene metallacycles Ag-2(1)(2)(PF6)(2) and Ag-2(2)(2)(PF6)(2) in high yield. Irradiation (UV light, lambda 365 nm) of Ag-2(1)(2)(PF6)(2) and Ag-2(2)(2)(PF6)(2) in [D-6]DMSO resulted in rapid conversion into the corresponding dinuclear cydobutane-carbene complexes Ag-2(3)(PF6)(2) and Ag-2(4)(PF6)(2) quantitatively. The cyclobutane-bridged polycarbene precursors were isolated in good yields as their tetrabenzimidazolium salts.
