2,6-Diisopropylphenylimidoneophylidene molybdenum(VI) bis(hexafluoro-t-butoxide) SCHROCK'S CATALYST

Technical Notes:
1. Unlike Mo(C oH12)(C 12H1N)(OC4Ho)2. the bis(hexafluoro-t butoxide) (MoFo) 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.
2.Useful for the "ring closing" of dienes or the coupling of terminal olefins.
3.Useful for cross-metathesis of alphatic alkenes with 2-vinyl aromatics.
