Homogeneous CO Hydrogenation: Ligand Effects on the Lewis Acid ...

NMR-scale Reaction of [1-P 2][BF 4] with 1 equiv [HPt][PF 6].
Under a nitrogen atmosphere, 28.5 mg (0.026 mmol) cation [1-P 2][BF 4] was dissolved in 0.5 mL
C 6D 5Cl in a 10 mL scintillation vial with stirring. Solid [HPt] + (16.9 mg, 0.026 mmol) was added
as a solid portionwise. After stirring for ten minutes, the cloudy solution was filtered through
microporous glass into an NMR tube, and spectra acquired, showing relatively high conversion
to carbene 2-P 2 (spectroscopic details above) in ~90% yield by 31 P integration.
