- 論文の詳細を見る
The <SUP>7</SUP>Li and <SUP>13</SUP>C NMR spectra have been observed for picolyl-type anions with lithium as a counter ion in polar solvents. With reference to the observed chemical shifts, it is concluded that these lithium salts are present in THF as tight ion pairs in which the anion-cation interaction takes place mainly at the ring nitrogen. Thus, the picolyl-type anions are characterized by their ion-pair structures.
