A highly effective hydroxylation reaction of aryl halides with water under synergistic organophotoredox and nickel catalysis is reported. The OH group of the resulting phenols originates from water, following deprotonation facilitated by an intramolecular base group on the ligand. Significantly, aryl bromides as well as less reactive aryl chlorides served as effective substrates to afford phenols with
报道了在协同的有机光氧化还原和镍催化下,芳基卤化物与水的高效羟基化反应。在配体上的分子内碱基促进去质子化之后,所得酚的OH基团起源于水。重要的是,芳基溴化物和反应性较低的芳基氯用作有效的底物,以提供具有广泛官能团的酚。不需要强大的无机碱或昂贵的贵金属催化剂,该方法可用于有效制备各种酚,并使多官能药学上相关的芳基卤化物羟基化。
