Bis(pentamethylcyclopentadienyl)ytterbium: An investigation of weak interactions in solution using multinuclear NMR spectroscopy
- Univ. of California, Berkeley, CA (United States)
NMR spectroscopy is ideal for studying weak interactions (formation enthalpy ≤20 kcal/mol) in solution. The metallocene bis(pentamethylcyclopentadienyl)ytterbium, Cp*2Yb, is ideal for this purpose. cis-P2PtH2complexes (P = phosphine) were used to produce slow-exchange Cp*2YbL adducts for NMR study. Reversible formation of (P2PtH)2 complexes from cis-P2PtH2 complexes were also studied, followed by interactions of Cp*2Yb with phosphines, R3PX complexes. A NMR study was done on the interactions of Cp*2Yb with H2, CH4, Xe, CO, silanes, stannanes, C6H6, and toluene.
