The Photooxidation of Bis(8-dimethylaminonaphthyl) Ditelluride

The photooxidation of (8-Me(2)NC(10)H(6)Te)(2) provided a complex reaction mixture from which the novel tetranuclear telluroxane cluster (8-MeNC(10)H(5)TeO)(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 center dot center dot center dot N bond turned into a covalent Te-N bond. In the solid-state, individual molecules of 1 are associated through secondary Te center dot center dot center dot O interactions giving rise to a 1D coordination polymer.
