The first stable and isolable alkanetellurenyl pseudohalides with the silver or potassium salts of the respective pseudoand pseudochalcogenides, tris(trimethylsily1)methanetellu-halides or pseudochalcogenides.
2-6Wegen der problematischen Handhabung von AgNs wird empfohlen, 6 durch Umsetzung von Tris(trimethylsily1)methantellurensaure-ethylester') mit Trimethylsilylazid darzustellen.Die Verbindungen Bis[tris(trimethylsilyl)methyltelluro]-carbodiimid (7) und -schwefeldiimid (8) wurden analog durch Umsetzung von 1 mit Ag,NCN bzw. KzNSN erhalten.
Synthesis of Stable Alkanetellurenyl Pseudohalides and PseudochalcogenidesThe first stable and isolable alkanetellurenyl pseudohalides with the silver or potassium salts of the respective pseudoand pseudochalcogenides, tris(trimethylsily1)methanetellu-halides or pseudochalcogenides. 5 -8 are also the first alkylrenyl cyanide, thiocyanate, selenocyanate, isocyanate, azide tellurium(I1) compounds with Te -N bonding. All compounds(2 -6) as well as bis[tris(trimethylsilyl)methyltelluro]carbodi-have been characterized by *H-, 13C-, 125Te-NMR, mass, and imide and -sulfur diimide (7,8) are obtained in high yields by IR spectroscopy. the reaction of tris(trimethylsilyl)methanetellurenyl iodide (1)
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
