Preparation and Characterisation of Five-Membered Tellurium-Containing Chalcogen-Nitrogen Ring Systems - Structure of [ClTeNSNS+]2[Cl-][AsF-6]The reaction of [(Me3Si)2N]2S with TeX4/SeCl4- or TeX4/SCl2 mixtures leads to the formation of covalent five-membered and , respectively. Treatment of 2a and 2b with Ag+Y- (Y- = BF-4, AsF-6, SbF-6) in liquid SO2 provides the cationic ring systems and 3d-f (X = Br). If the solvent is CH2Cl2 the double salts and 4d-f (X = Br) are obtained. The structure of has been determined by X-ray crystallography. The selenium-containing five-membered ring systems are accessible by reaction of AgAsF6 with 1a and 1c, respectively.
