Abstract:
The title compound, C(8)H(4)ClNO(2)Te, represents the first reported example of a benzofuran-derived 2,1,3-benzoxatellurazole derivative. While it can be formally described as a nitrosoaryltellurium monochloride, its Te-O and Te-C bond lengths of 2.1421 (14) and 2.0374 (17) Å, respectively, characterize it as a planar tricyclic aromatic containing a Te=C double bond. Its formation suggests that derivatives of 2-cyclohexenone oxime in general react with tellurium dioxide to form aryl-2,1,3-benzoxatellurazoles.

Nomenclature of Aromatic Compounds with Multiple Substituents
For disubstituted benzene derivatives, with two groups attached to the benzene ring, three constitutional isomers are possible. For example, consider dimethyl benzene, often called xylene, where the second methyl group can be substituted at the second, third, or fourth carbon. The relative position of the substituents is represented by prefixes ortho, meta, or...
