Neue Selen-Stickstoff-Verbindungen tert-Butyl-seleninylamin, ButNSeO, und Di(tert-butyl)selendiimid, Se(NBut)2/New Selenium-Nitrogen Compounds tert-Butyl-seleninylamine, ButNSeO, and Di(tert-butyl)selenium Diimide, Se(NBut)2

The first seleninylamine, tBuNSeO, was prepared from tert-butylamine, tBuNH2, and SeOCl2 (3:1). The selenium diimide Se(NBut)2 was isolated from the corresponding reaction of tBuNH2 and SeCl4 (6:1); it decomposes at ambient temperature to give cyclic Se3(NBut)2. The new compounds were characterized on the basis of their IR , 1H and 13C NMR and mass spectra.
