| description | A series of aminophosphines were prepared by controlled condensation reaction between PCl<sub>3</sub> or PhPCl<sub>2</sub> and amines, and they were converted into the corresponding chalcogenides. <sup>31</sup>P-NMR and mass spectral data were collected for characterization of these asymmetrically substituted phosphines, and in addition, <sup>77</sup>Se- NMR data were collected for the phosphine selenides prepared. The spectral data revealed the importance of the dipolar structure for the heavier chalcogen atoms and the π-bond structure for the lighter ones. This study has also brought out the first examples of chiral tris(amino)phosphines and the corresponding selenides. |
