Thiophene-Fused π-Systems from Diarylacetylenes and Elemental Sulfur.

Journal of the American Chemical Society

Meng L, Fujikawa T, Kuwayama M, Segawa Y, Itami K.
PMID: 27501373
J Am Chem Soc. 2016 Aug 17;138(32):10351-5. doi: 10.1021/jacs.6b06486. Epub 2016 Aug 08.

A simple yet effective method for the formation of thiophene-fused π-systems is reported. When arylethynyl-substituted polycyclic arenes were heated in DMF in the presence of elemental sulfur, the corresponding thiophene-fused polycyclic arenes were obtained via cleavage of the ortho-C-H...
