environmentally benign character of iron mean that it is an ideal alternative to precious metals in catalysis. Recent growth in the number of iron-catalysed reactions reported reflects an increasing demand for sustainable chemistry. Only a limited number of chiral iron catalysts have been reported and these have, in general, proven less enantioselective than other transition-metal catalysts, thus limiting their
铁的易得性、低廉的价格和环境友好的特性意味着它是催化中贵金属的理想替代品。最近报道的铁催化反应数量的增长反映了对可持续化学的需求不断增加。仅报道了有限数量的手性铁催化剂,并且通常证明这些手性铁催化剂的对映选择性低于其他过渡金属催化剂,因此限制了它们的吸引力。在这里,我们报告螺-双恶唑啉配体的铁配合物是不对称 O-H 键插入反应的高效催化剂。这些配合物催化插入各种醇甚至水的 O-H 键,在温和的反应条件下具有出色的对映选择性。选择性超过了用其他过渡金属催化剂获得的选择性。
