FIRST EXAMPLES OF DISELENO TWEEZER-LIKE LIGANDS: SYNTHESIS, CHARACTERIZATION AND Pt(II) CYCLOMETALATION

Abstract The synthesis of the first examples of diseleno tweezer-like molecules is described starting from diselenocyanobenzenic or pyridinic compounds and chloronaphthyl or anthryl derivatives. The new diselenides are characterized by mass spectrometry and multinuclear NMR spectroscopy. Starting from naphthyl derivatives, it was unambigously demonstrated for the first time their cyclometalation with Pt(II) to form metalloreceptors.
