Popis: The synthesis of 2-(1-(prop-2-yn-1-yl)-1H-pyrazol-3-yl)pyridine is presented. This ligand contains both, an alkynyl function being suitable for metal-carbon bond formation with electron-rich late transition metal sites, and a pyrazolylpyridine unit, which is well-known to undergo chelation reactions similar to 2,2′-bipyridine. This strategy allows building up polynuclear complexes with broad combinations of different metal sites. Two platinum alkynyl complexes were structurally characterized, and a trinuclear Ru2Pt complex was indentified by means of NMR spectroscopy and ESI mass spectrometry.
