    • The thiophene ring structure is widespread in nature, and many of the thiophene derivatives are biologically active. Thiophene derivatives are also widely utilized as functional materials in dyes and liquid crystals and as components of organic conducting polymers. For reviews, see: (a) Russell, R. K.; Press, J. B.

In these two reports, reaction of 4-phenyl-3-butyn-2-one and 1-phenyl-1-pentyn-3- one with carbon disulfide in the presence of sodium hydride in DMF followed by alkylation afforded a mixture of isomeric 2-alkylthio-6-phenyl-4H-thiopyrans and 5-alkylthio-2-benzylidene-3(2H)-thiophenones in a ratio of about 4:1.
