The Photooxidation of Bis(8‐dimethylaminonaphthyl) Ditelluride

The photooxidation of (8‐Me₂NC₁₀H₆Te)₂ provided a complex reaction mixture from which the novel tetranuclear telluroxane cluster (8‐MeNC₁₀H₅TeO)₄ ( 1 ) was isolated in 17 % yield. Compound 1 contains two 5,5′‐binaphthyl moieties that presumably formed by oxidation of C5–H bonds of the naphthyl ring. Upon formation of 1 , one of the two methyl groups of the 8‐dimethylamino group was cleaved and the remaining coordinative Te···N bond turned into a covalent Te–N bond. In the solid‐state, individual molecules of 1 are associated through secondary Te···O interactions giving rise to a 1D coordination polymer.
