deuteration of six-membered cyclic sulfinylated radicals were investigated. For this purpose, radicals with the predefined conformations I and II were generated from 2-(phenylselenenyl)thiacyclo-hexane-1-oxide derivatives 7–10 (Scheme). Steric effects were insufficient to account for all the observed selectivities. The participation of stereoelectronic effects are envisaged to explain the stereoselective axial
研究了六元环亚磺酰化基团的烯丙基化和氘代。为此,从2-(苯基硒烯基)硫代环己烷-1氧化物衍生物7-10(方案)生成了具有预定义构象I和II的基团。立体效应不足以说明所有观察到的选择性。设想了立体电子效应的参与以解释II型自由基的立体选择性轴向氘代。
