在较短的反应时间（6 h）下，以较高的收率（80%）制备了PhHP(CH2)nPHPh, n = 2,3，并转化为[{PhHP(CH2)nPHPh}W(CO)4]的中位和异构体，n = 2,3。根据配合物的13C NMR谱计算了12/13C同位素对31P屏蔽和| - 2JP-P - |耦合的影响。
The disecondary phosphines PhHP(CH2)nPHPh, 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.
