- 論文の詳細を見る
Charge distributions in vinyl methyl and divinyl ethers and their sulfur homologs bearing a polar substituent at the <I>trans</I>-β position were calculated by the CNDO/2 method. It was found that the effect of substituents on charge distribution is transmitted primarily through the successive π-polarization of the ethylenic units involved. In the divinyl compounds, the sulfur atom on the spd basis is calculated to transmit the substituent effects more effectively than the oxygen atom. The greater transmission efficiency of the sulfur atom is interpreted in terms of the pπ-dπ-pπ conjugation.
