概要
- 論文の詳細を見る
The most predominant conformation of 4-(2-thienyl)-3-butene-2-one and methyl β-(2-thienyl)acrylates were determined by the analysis of their LIS's. The LIS's toward higher fields were observed with some ring protons (H<SUB>3</SUB>'s and some of H<SUB>4</SUB>'s), and were best interpreted by assuming that about 20% of the shift reagent coordinates on the methoxyl oxygen atom and the rest on the carbonyl oxygen atom.
