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)nPHPh}-W(CO)4], n = 2, 3. 12/13C isotope effects on 31P shieldings and |2JP-P| couplings have been calculated from the 13C NMR spectra of the complexes.
