Lunazzi, L. published the artcileConformational analysis in heteroaromatic carbonyl compounds. I. Radical anions of 2,5-thiophenedicarboxaldehyde and related derivatives, Category: amides-buliding-blocks, the publication is Journal of the Chemical Society, Perkin Transactions 2: Physical Organic Chemistry (1972-1999) (1972), 751-4, database is CAplus.
The room temperature ESR spectrum of the photolytically generated radical anion of 2,5-thio-phenedicarboxaldehyde (I) showed the existence of 2 of the 3 possible rotational isomers. The less stable was the O-cis-trans isomer as seen from the nonequivalence of the thiophene proton splittings. Examination of several derivatives of I, e.g. thieno[3,2-b]-thiophene-2,5-dicarboxaldehyde, with different steric requirements allowed the assignment of the O-cis-cis conformation to the other rotamer.
