概要

• 論文の詳細を見る

• <SUP>1</SUP>H and <SUP>13</SUP>C NMR spectra are reported for substituted 2-(2-nitrovinyl) thiophenes. The proton chemical shifts and coupling constants were correlated closely with those of methyl <I>trans</I>-3-(5-substituted 2-thienyl) acrylates. We have found that the additivity rule for <SUP>13</SUP>C chemical shifts of simple substituted thiophenes is applicable to the shifts of the ring carbons in substituted 2-(2-nitrovinyl) thiophenes.
