In the presence of a catalytic amount of a phosphine, elemental tellurium efficiently inserts into Sn-Sn and Pb-Pb bonds under mild conditions to give the corresponding tellurides R3MTeMR3 (M = Sn, Pb) in quantitative yield. Mechanistic study shows that first a phosphine telluride R′3P=Te is formed via the reaction of R′3P with tellurium, which subsequently reacts with (R3M)2 to produce (R3M)2Te and concomitantly regenerates R′3P to restart another cycle of the catalytic insertion.

New preparations for the following compounds are described: Te(SCF3)2, Te(NSO)2, and Cl2Te(NSO)2.The catalytic or thermal SO2 elimination from Cl2Te(NSO)2 affords a coordinated or non-coordinated thiachalcogenadiazole.Conversions of these compounds are reported.Evidence for the proposed mechanism for the reaction between Te(NSO)2 and SbCl5 is provided.Cl4Te2N2(SCF3)2, prepared from TeCl4 and CF3SN(SiMe3)2, reacts with LiN(SiMe3)2 to form 4Te2N2(SCF3)2.An X-ray structural analysis of Cl4Te2N2(SCF3)2 is presented. - Key Words: Tellurium, bis(sulfinylamido)-, bis(trifluoromethylthio)- / Thiachalcogenadiazole / Ditelluradiazetidine
