The reaction of (Me3Si)2NLi aith SCl2 and elemental sulfur or with Se2Cl2 and elemental selenium leads to the formation of mixtures of bissulfides and selenides 2Ex (E = S or Se; x = 1-4).The reaction products were identified by mass spectroscopy as well as by 77Se and 13C NMR spectroscopy.The reaction of (Me3Si)2NH with S2Cl2 produces 2S3 as the main product with only traces of other aminosulfides. 2S3 was purified by distillation under reduced pressure and identified by elemental analysis, mass spectroscopy, and by 1H, 13C, and 14N NMR spectroscopy.The successful cyclocondensation reaction of 2S3 with SCl2 and SO2Cl2 produces S4N2 in 72percent yield and provides further verification of the identity of bistrisulfide.While the analogous reaction of (Me3Si)2NH with Se2Cl2 also leads to the formation of 2Se3 (48 mol percent) as the main product, the reaction mixture contains 2Se2 and 2Se4 in significant amounts (17 and 35 mol percent, respectively).Attempts to purify the mixture by distillation under reduced pressure resulted only in the formation of a 83:17 mixture of 2Se2 and 2Se3. - Keywords: Bissulfides; Bisselenides; Tetrasulfur Dinitride; NMR Spectra; Mass Spectra
