selective catalytic hydroxylation of arenes remains an ongoing research challenge because of the relative inertness of aryl carbon-hydrogen bonds, the higher reactivity of the phenolic products leading to over-oxidized by-products, and the frequently insufficient regioselectivity. We report that iron coordinated by a bioinspired l-cystine–derived ligand can catalyze undirected arene carbon-hydrogen hydroxylation
由于芳基碳氢键的相对惰性、酚类产物的较高反应性导致过度氧化的副产物以及经常不足的区域选择性,芳烃的可持续、非定向和选择性催化羟基化仍然是一项持续的研究挑战。我们报告说,铁由受生物启发的l-胱氨酸衍生的配体可以催化非定向芳烃碳氢羟基化,过氧化氢作为末端氧化剂。该反应以其广泛的底物范围、出色的选择性和良好的产率而著称,并且表现出与氧化敏感官能团的相容性,如醇、多酚、醛,甚至硼酸。该方法非常适合通过多重碳氢羟基化合成多酚,以及天然产物和药物分子的后期功能化。
