| 摘 要： | The reaction of N-substituted-benzenesulfonyl-N'-(4,6-disubstituted-s-triazin-2-yl)-ethylene diamines with tri(dialkylamine)phosphine has been studied and the cyclic products have been obtained by one-pot reaction. It was found from ~1H NMR and ~(13)C NMR analyses that the single bond rotation between the nitrogen atom 3 in the 1,3,2-diazaphospholidines and the carbon atom 2 in the s-triazine was hindered at room temperature, which was further confirmed by X-ray diffraction results. The most stable conformation of the phosphorous heterocycle is envelope-form. From the bond length and the hybridization of the nitrogen atom outside the ring, it was deduced that there was a certain contribution of dπ-pπ bond between P and N atoms.
