N2  - It has been shown that condensation of thiophen-2-aldehyde with 2-thienyl- acetonitrile gives trans-&#945; &#946;-di-(2-thienyl)acrylonitrile; but condensation of thiophen- 2-aldehyde with 2-thienylacetic acid yields cis-&#945;,&#946;-di-(2-thienyl)acrylic acid. Similarly, condensation of thiophen-2-aldehydes with 2,5-biscyanomethylthiophen gave trans-trans-&#946;,&#946;'-di-(2-thienyl)-&#945;,&#945;'-(2,5-thiophen)diacrylonitriles; but condensation with thiophen-2,5-diacetic acid gave cis-cis-&#946;,&#946;'-di-(2-thieny1)-&#945;,&#945;'-(2,5-thio-phen)diacrylic acids.
