Synthesis, structure, electrochemistry and ROMP-activity of new ferrocenyl analog of Grubbs’ metathesis catalyst
Treatment of [(PCy 3) 2Cl 2Ru CH–Ph] ( I) with vinylferrocene 1 and 1-ferrocenyl-1,3-butadiene 2 yielded solid products. These new complexes were characterized by 1H NMR, 31P NMR and 13C NMR spectroscopy. Treatment of [(PCy 3) 2Cl 2Ru CH–Ph] ( I) with vinylferrocene 1 and 1-ferrocenyl-1,3-butadiene...

Treatment of [(PCy

CH–Ph] (
I) with vinylferrocene
1 and 1-ferrocenyl-1,3-butadiene
2 yielded solid products. These new complexes were characterized by
1H NMR,
31P NMR and
13C NMR spectroscopy. X-ray crystal structures of both the complexes have been solved. The crystal structure of
II confirmed the assigned structure and revealed existence of two sets of intermolecular C–H–Cl(M) type interactions, viz. (Ru)Cl–H–C(ferrocene) and (Ru)Cl–H–CHCl
2. The air-stable, dark solid
II is an efficient catalyst for ring-opening metathesis polymerization (ROMP) of cyclopentene, norbornene and cycloocta-1,5-diene. Electrochemical behavior of the complexes clearly reflects electronic communication between two metal centers. |
