摘要
The electron-rich platinum(II) derivatives [Pt(R)(2)(DMSO)(2)] (R = Me, Ph) react with 2-vinylpyridine (L) to give the cyclometalated complexes [Pt(L-H)(R)(DMSO)] through C-H bond activation. Cyclometalation also occurs with [Pt(Me)(Cl)(DMSO)(2)]. From the starting compounds, a series of cyclometalated complexes was obtained and characterised by analytical and spectroscopic methods. The molecular structures of [Pt(L-H)(Me)(PPh3)] and [Pt(L-H)(Ph)(PCy3)] were solved by X-ray diffraction analysis, and the results unambiguously demonstrate cyclometalation of 2-vinylpyridine. The five-membered cyclometalated ring is particularly stable, likely due to partial electronic delocalisation.
