スポンサーリンク
概要
- 論文の詳細を見る
Configurational stabilities of optically active diaryl selenoxides are examined under several conditions such as acidic, basic, or in the presence of water. It is found that the diaryl selenoxide which has two hindered <I>t</I>-butyl groups on the ortho positions is relatively stable toward racemization even under acidic conditions. Mechanism of racemization is ascertained to be via formation of the achiral hydrate (R–Se(OH)<SUB>2</SUB>–R′) by the observation of oxygen exchange on the selenium atom.
