 Title    Determination of the Enantiomeric Excess of Horner Phosphines by 13C NMR Spectroscopy. A 13C and 31P NMR Study of the Diastereomeric Complexes Formed with [i/3-(+)(lR ,5R )-Pinenyl]nickel Bromide Dimer  
 Abstract    ohlenforschung, K aiser-W ilhelm -Platz 1, D-4330 M ülheim a. d. Ruhr, Federal Republic o f G erm any The 13C and 31P N M R data o f the H orner phosphines PRR'R" [R — M e. R' = f-Bu. R" = Ph (2) or /-Pr (4)] and their diastereom eric 1:1 adducts with [?73-(+) (l R .5R)-pinenyl]nickel bromide dimer (3) and (5), respectively, are reported. It is shown that the optical purities of the phosphines can be deduced easily from the N M R spectra. N ot only are these values in very good agreem ent with those obtained from optical rotatory data but they are also obtained much more con ve­ niently.
