遷移金属触媒を用いた酸化的条件下における炭素-炭素不飽和結合とスルフィン酸ナトリウムとの反応

抄録

A copper-catalyzed sulfonylation of alkenes or alkynes was performed using sodium sulfinates under oxidative conditions. These reactions afforded numerous alkenyl sulfones stereoselectively. For instance, the reaction using alkenes efficiently gave (E)-alkenyl sulfones in the presence of potassium iodide. The sulfonylation of alkynes produced (E)-alkenyl sulfones or (E)-β-haloalkenyl sulfones in good yields.  Furthermore, a palladium-catalyzed arylation of terminal alkenes with sodium sulfinates could synthesize (E)-alkenes via the desulfonylation in air.
