active and enantioselective ion‐pair sulfoxidation catalyst, consisting of an achiral iron(III)‐salen cation and a chiral phosphate counteranion, mediates the oxidization of various sulfides with high yields and enantioselectivities. The enantioselectivities observed, especially for electron‐poor substrates, represent the best results so far in manganese and iron‐salen systems. This work represents the
由非手性铁(III)-salen阳离子和手性磷酸抗衡离子组成的高活性和对映选择性离子对硫氧化催化剂,可高产率和对映选择性地介导各种硫化物的氧化。观察到的对映选择性,特别是对于贫电子底物,是迄今为止在锰和铁salen体系中的最佳结果。这项工作代表了我们的不对称抗衡阴离子导向催化(ACDC)概念在铁催化中的首次应用。
