1,2-Di-2-thienyl-2-hydroxyethanone (2,2′-thenoin)

Abstract

The title compound, C10H8O2S2, is the 2‐thienyl symmetric analog of benzoin. 2,2′–Thenoin can be synthesized in good yield utilizing the benzoin condensation reaction (starting with 2‐thio­phene­carbox­aldehyde). The crystal structure of 2,2′‐thenoin has been determined at room temperature.

6-Nitro-2,3-bis(thiophen-2-yl)quinoxaline

“…2-Thiophenecarboxaldehyde was condensed to 2,2 0 -thenoin (Crundwell et al, 2002) followed by oxidation to 2,2 0 -thenil (Crundwell et al, 2003). The nitrophenylenediamines were used as purchased from Sigma-Aldrich.…”
