Abstract
The disecondary phosphines PhHP(CH2)(n)PHPh, n = 2, 3, have been prepared i n 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-1 2/13 isotope effects on P-31 shieldings and \(2)J(P-P)\ couplings have been calculated from the C-13 NMR spectra of the complexes.
