  Further Improvements in the Preparation of Disecondary Phosphines PhHP(CH₂)_nPHPh, n = 2, 3, and Their Tetracarbonyltungsten Complexes:  Analysis of Their Multinuclear NMR Spectra

  摘要：

  The disecondary phosphines PhHP(CH2)(n)PHPh, n = 2, 3, have been prepared in high yields (80%) after short reaction times (6 h) and converted into the meso- and rac-diastereomers of [{PhHP(CH2)(n)PHPh}W(CO)(4)], n = 2, 3. C-12/13 isotope effects on P-31 shieldings and \(2)J(P-P)\ couplings have been calculated from the C-13 NMR spectra of the complexes.

  Improved preparations of the disecondary phosphines PhHP(CH2)(n)PHPh (n = 2, mppe; n = 3, mppp; n = 4, mppb; n = 6, mpph) by the lithium cleavage of the corresponding ditertiary phosphine Ph2P(CH2)(n)PPh2 are described and various NMR parameters are reported ; a C-12/13 isotope effect upon delta(P-31) is observed in the case of mppe. Reactions of mppe and mppp with [M(CO)6] (M = Cr, Mo, W) yield 1:1 complexes; both the meso and the rac isomers are produced, are separated and are unequivocally characterized by elemental analysis, vibrational spectroscopy and H-1, C-13 and P-31 NMR spectroscopy.
