Unlike Mo(C10H12)(C12H17N)(OC4H9)2, the bis(hexafluoro-t-butoxide) (MoF6) derivative will metathesize many ordinary olefins, especially terminal olefins, and will ROMP many norbornene or substituted norbornadiene monomers to give all cis, and often isotactic, polymers.
Useful for the "ring-closing" of dienes or the coupling of terminal olefins.
Useful for cross-metathesis of alphatic alkenes with 2-vinyl aromatics.
