Abstract

<abstract abstract-type="main" xml:lang="en"> <title> <x xml:space="preserve">Abstract</x> </title> <p>The title compound, C₈H₄ClNO₂Te, 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.</p> </abstract>
