  Abstract A convenient, rapid H2SO4-promoted regioselective monobromination reaction with N-bromosuccinimide was developed. The desired para-monobrominated or ortho-monobrominated products of phenol derivatives were obtained in good to excellent yields with high selectivity. Regioselective chlorination and iodination were also achieved in the presence of H2SO4 using N-chlorosuccinimide and N-iodosuccinimide

  公开（公告）日：2019-08-20

  本发明公开一种在水相中光催化合成多溴代苯酚化合物的方法，其步骤如下:在反应容器中加入催化量的自由基引发剂、苯酚衍生物以及低毒、价廉的溴盐和水，室温条件下，5 W功率下置于光催化反应仪中反应，一定时间后，用乙酸乙酯萃取后重结晶获得多溴代苯酚化合物；上述自由基引发剂为曙红、偶氮二异丁醇、过硫酸钠、过硫酸铵或过硫酸钾。该方法自由基引发剂和溴盐均价廉易得，是一种理想的多溴代苯酚化合物的合成方法。本方法使用低毒的溴盐代替液溴进行溴化反应，以价廉易得的自由基引发剂代替不稳定且易爆的过氧化氢，使用新兴的光催化的方法，仅仅使用5 W的功率灯反应便可高产率的得到多溴代苯酚化合物，反应选择性较高，副产物少，后处理简单。

  phenol changes from F via Cl, OCH3, C(CH3)3, and H to CH3. The polar effect in phenol bromination by the enzymatic method, according to a Hammett-correlation (ρ=−3), compares to reactivity of molecular bromine under identical conditions (ρ=−2). Hypobromous acid is not able to electrophilically substitute bromine for hydrogen at pH 6.2 in aqueous tert-butanol. The tribromide anion behaves in MES-buffered

  如果用溴化钠，过氧化氢和褐色藻类Ascophyllum nodosum的钒酸盐（V）依赖性溴过氧化物酶I处理，则苯酚和邻位取代衍生物可提供选择性对溴化的产物。在吗啉-4-基-乙烷磺酸溴化的相对速率（MES）缓冲的含水叔丁醇（pH值6.2）由系数32增加，作为邻位-取代的选自F地通过Cl，OCH苯酚变化3，C（ CH 3）3，并且H至CH 3。根据Hammett相关性（ρ= −3），与在相同条件下（ρ = −2）的分子溴的反应性进行了比较。在氢叔丁醇中，次溴酸不能用pH 6.2的氢亲电子取代溴。三溴化物阴离子在MES缓冲的叔丁醇水溶液中表现为亲电体（ρ −-3），在苯酚溴化中显示出与分子溴相似的极性效应。

  synthetic protocol to realize aromatic perfluoro-tert-butylation. The key to the success is the identification of PFtB phenyl sulfone as a new source of PFtB anion, which reacts with arynes in a highly regioselective manner to afford perfluoro-tert-butylated arenes in high yields. The application of the method is demonstrated by the preparation of sensitive 19F-labeled NMR probes with an extraordinary resolving
