Synthesis of Stable Alkanetellurenyl Pseudohalides and Pseudochalcogenides: (Me 3 Si) 3 CTeX (X=– CN, – SCN, – SeCN, – NCO, – N 3 ) and (Me 3 Si) 3 CTe–Y – TeC(SiMe 3 ) 3 (Y=– NCN–, – NSN–) The first stable and isolable alkanetellurenyl pseudohalides and pseudochalcogenides, tris(trimethylsilyl)methanetellurenyl cyanide, thiocyanate, selenocyanate, isocyanate, azide ( 2 – 6 ) as well as bis[tris(trimethylsilyl)methyltelluro]carbodiimide and ‐sulfur diimide ( 7, 8 ) are obtained in high yields by the reaction of tris(trimethylsilyl)methanetellurenyl iodide ( 1 ) with the silver or potassium salts of the respective pseudohalides or pseudochalcogenides. 5 – 8 are also the first alkyltellurium(II) compounds with Te–N bonding. All compounds have been characterized by 1 H‐, 13 C‐, 125 Te‐NMR, mass, and IR spectroscopy.
