Tungsten-Catalyzed Alkyne Metatheses in Transition-Metal Coordination Spheres: Versatile New Syntheses of Metallamacrocycles Academic Article uri icon

abstract

  • The title reaction (10-15 mol % of (t-BuO)3W-(≡C-t-Bu), chlorobenzene, 80°C) is applied to octahedral and square-planar 18- and 16-valence-electron rhenium, ruthenium, and platinum complexes with cis- or trans-Ph2P(CH2)6C≡CCH3 ligands. NMR analyses show ca. 90-70% educt conversions, and 17-membered diphosphine chelates have been isolated in 59-47% yields and crystallographically characterized.
