Selenonium imides 1 and 2, stabilized by intramolecular coordination of the amino group of 8-dimethylamino-1-naphthyl substituent to the selenium atom, were synthesized. Optically active selenonium imides were obtained by chromatographic resolution on optically active columns and were found to be stable toward racemization both in the solid state and in solution. Absolute configurations of the optically active selenonium imides were assigned on the basis of specific rotations and circular dichroism spectra.
通过 8-二甲基氨基-1-萘取代基的氨基与硒原子的分子内配位,合成了稳定的硒鎓亚胺 1 和 2。通过在光学活性色谱柱上进行色谱解析,得到了具有光学活性的硒铵亚胺,并发现它们在固态和溶液中对消旋化都很稳定。根据特定旋转和圆二色光谱,确定了光学活性硒铵亚胺的绝对构型。
