(183)W NMR Spectroscopy Guides the Search for Tungsten Alkylidyne Catalysts for Alkyne Metathesis

Triarylsilanolates are privileged ancillary ligands for molybdenum alkylidyne catalysts for alkyne metathesis but lead to disappointing results and poor stability in the tungsten series. (1)H,(183)W heteronuclear multiple bond correlation spectroscopy, exploiting a favorable (5) J‐coupling between t...
