Abstract

Organotellurium oligomers with different lengths of the telluride fragments and hydrocarbon chains were synthesized by reactions of tellurium with organic dihalogen derivatives in the system hydrazine hydrate-KOH. Oligomers containing two and three contiguous tellurium atoms in the solid state give rise to strong ESR signals with a g value of 2.005–2.030 and a line width of 180–290 Oe. The possibility for formation of tellurium-centered radicals is discussed. Nitrosodurene as radical scavenger in chloroform solution trapped neither primary radical species nor radical products derived therefrom.
