We succeeded in the measurement of ¹⁸³W NMR spectra of tungsten complexes having an anionic oxygen-containing ligand. These complexes are precatalysts for ring-opening metathesis polymerization. We will present detailed measurement conditions and chemical shifts of the ¹⁸³W of the various complexes.
