Olefin Metathesis. IV.

Journal of Japan Oil Chemists' Society, 1976
The metathesis of methyl oleate with the WCl6-cocatalyst system was investigated. Tetra-n-butyl-stannane, tetraethylstannane and triethylaluminum were effective as cocatalysts. The optimum reaction condition was considerably different from that for the metathesis of internal alkene having no functional group.

Ring Opening Metathesis Polymerization of Cyclic Olefins by PMe3–Supported (Arylimido)Niobium–Alkylidene Catalysts

Macromolecular Chemistry and Physics, Volume 227, Issue 11, 16 June 2026.
(Arylimido)niobium(V)–alkylidene catalysts containing pentafluorophenylimido ligand, Nb(CHR)(NC6F5)(OC6X5)(PMe3)2 (R = CMe2Ph, X = F; R = SiMe3, X = Cl), show rather low catalytic activity than the 2,6‐dihalophenylimido catalysts, Nb(CHSiMe3)(N‐2,6‐X2C6H3)(OC6X5)(PMe3)2 in ring opening metathesis polymerization (ROMP) of norbornene.
