aliphatic substrates, the catalyst was found to activate itself to a FeIIIFeIVL. active species able to catalyze aliphatic amination. Extensive DFT calculations show that this activation event drastically enhances the electron affinity of the active species to match the substrates requirements. Overall this process consists in a redox self‐adaptation of the catalyst to the substrateneeds.
用于形成碳-杂原子键的铁催化剂的开发在绿色化学和氮转移的背景下引起了浓厚的兴趣,已经成为通用的胺合成方法中最有希望的方法。先前开发的二铁体系由于具有Fe III Fe IV活性物种而被证明在催化磺酰亚胺化和叠氮化中有效。处理更苛刻的苄基和脂族底物,发现该催化剂本身激活到的Fe III的Fe IV大号。能够催化脂肪族胺化的活性物质。大量的DFT计算表明,这种激活事件极大地增强了活性物质的电子亲和力,从而满足了底物的要求。总体而言,该过程包括催化剂对基材需求的氧化还原自我适应。
