The room-temperature 1H n. m. r. spectrum of (1) in <²H8>toluene contains a cyclopentadienyl resonance at δ 2.29; upon cooling to -60 deg C this moves to δ 1.91.This high-field chemical shift is ascribed to the shielding effect of the aromatic ring current of a phenyl ring of the PPh3 ligand.The X-ray crystal structure of (1) is reported; the crystals are orthorhombic, space group Pc2₁n with a = 10.161(2), b = 15.735(3), c = 19.256(5) Angstroem, and Z = 4.The structure was solved via the heavy-atom method and refined to R = 0.028 using 2137 independent reflections.Reaction of compound (1) with trimethyl phosphite gives (2) and with AgBF4 and (+)-PhCH(Me)NH2 yields the diastereoisomers of (3).
