A series of organoselanyl- and organotellanyl-substituted ethyl- and propylamines and their hydrochlorides, as well as 2-(methylsulfanyl)ethylamine have been synthesized. Efficient general synthetic routes have been developed to chalcogen(S, Se, Te)-containing Schiff bases with di- and trimethylene bridges between the nitrogen atom of the imino group and the chalcogen, by condensation of 3-(tert-butyl)- and 3-(1-ethylpropyl)-2-hydoxybenzene-carbaldehydes with the amines. The influence of the organylchalcogenyl-group on some spectral characteristics (1H, 13C, 77Se NMR spectroscopy) of both amines and Schiff bases is discussed.
我们合成了一系列有机硒基和有机噻吩基取代的乙胺和丙胺及其盐酸盐,以及 2-(甲硫基)乙胺。通过 3-(tert-butyl)- 和 3-(1-ethylpropyl)-2-hydoxybenzene-carbaldehydes 与胺的缩合,开发出了含查尔根(S、Se、Te)的希夫碱的高效通用合成路线,在亚氨基的氮原子和查尔根之间具有二亚甲基和三亚甲基桥。本文讨论了醛基对胺和席夫碱的一些光谱特性(1H、13C、77Se NMR 光谱)的影响。
