A New Route to Heterobimetallic C3 Complexes via C⋮C Metatheses of 1,3-Diynyl Ligands: Synthesis and Structure of (η5-C5Me5)Re(NO)(PPh3)(C⋮CC⋮)W(O-t-Bu)3 Academic Article uri icon


  • Reactions of (η5C5Me5)Re(NO)(PPh3)(C≡ CC≡CR) (R = Me, H) and (t-BuO)3W≡W(O-t-Bu)3give (t-BuO)3W≡CR and the title complex (79-76%), which crystallizes from toluene as a solvated tert-butoxybridged dimer. The NMR, IR, and crystallographic properties establish dominant Re-C≡C-C≡W as opposed to+Re=C=C=C=W-character.
