A new flavin catalyst 2 immobilized in an ionic liquid ([BMIm]PF6) was used for the highly selective oxidation of sulfides to sulfoxides by hydrogen peroxide. The sulfoxides were obtained in good to high yields and high selectivity without any detectable overoxidation to sulfone. The catalyst in the ionic liquid was recycled up to seven times without loss of activity or selectivity.
固定在离子液体([BMIm] PF 6)中的新型黄素催化剂2用于过氧化氢将硫化物高度选择性地氧化为亚砜。亚砜以良好至高产率和高选择性获得,而没有任何可检测到的过氧化成砜。离子液体中的催化剂可循环使用七次,而不会损失活性或选择性。
