Treatment of 2, 2′‐dibromodiphenylacetylene 7 with tert ‐butyllithium followed by tellurium insertion resulted in intramolecular ring closure to afford [1]benzotelluro[3,2‐ b ][1]benzotellurophene 8a . Similarly, [1]benzoseleno‐[3,2‐ b ][1]benzoselenophene 8b and [1]benzothieno[3,2‐ b ][1]benzothiophene 8c were also obtained.
