Numerous areneselenenamides derived from ammonia, primary and secondary amines and two N,N-bis(arylseleno)alkylamines have been studied. The selenenamides bearing an electron-withdrawing substituent on the aromatic moiety are stable. The 1H, 13C and 77Se chemical shifts and some coupling constants are reported. For N.N-dialkyl-o-nitrobenzeneselenenamides, the 77Se NMR and the 17O NMR give evidence of an Se-O interaction. In N-alkyl derivatives, a hydrogen bond between the amine group and the ortho-substituent is proposed to explain the deshielding of the selenium nucleus.
研究人员对从氨、伯胺和仲胺以及两种 N,N-双(芳基硒)烷基胺中提取的大量硒酰胺进行了研究。在芳香族分子上带有取电子取代基的硒酰胺是稳定的。报告了 1H、13C 和 77Se 化学位移以及一些耦合常数。 对于 N.N-二烷基-邻硝基苯硒酰胺,77Se NMR 和 17O NMR 显示了 Se-O 相互作用的证据。在 N-烷基衍生物中,胺基团和正交取代基之间的氢键被提出来解释硒核的去屏蔽作用。
