Abstract

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 |²J_P-P| couplings have been calculated from the ¹³C NMR spectra of the complexes.
