  C−H Activation/Borylation/Oxidation:  A One-Pot Unified Route To Meta-Substituted Phenols Bearing Ortho-/Para-Directing Groups

  摘要：

  An efficient one-pot C-H activation/borylation/oxidation protocol for the preparation of phenols is described. This method is particularly attractive for the generation of meta-substituted phenols bearing ortho-/para-directing groups, as such substrates are difficult to access by other phenol syntheses.

  A process to synthesize substituted phenols such as those of the general formula RR′R″Ar(OH) wherein R, R′, and R″ are each independently hydrogen or any group which does not interfere in the process for synthesizing the substituted phenol including, but not limited to, halo, alkyl, alkoxy, carboxylic ester, amine, amide; and Ar is any variety of aryl or hetroaryl by means of oxidation of substituted arylboronic esters is described. In particular, a metal-catalyzed C—H activation/borylation reaction is described, which when followed by direct oxidation in a single or separate reaction vessel affords phenols without the need for any intermediate manipulations. More particularly, a process wherein Ir-catalyzed borylation of arenes using pinacolborane (HBPin) followed by oxidation of the intermediate arylboronic ester by OXONE is described.

  描述了一种合成取代酚的过程，如通式RR′R″Ar(OH)中的那些，其中R、R′和R″分别独立地是氢或不干扰合成取代酚过程的任何基团，包括但不限于卤素、烷基、烷氧基、羧酸酯、胺、酰胺；Ar是芳基或杂芳基的任何种类，通过氧化取代芳基硼酸酯来实现。具体地，描述了一种金属催化的C—H活化/硼化反应，随后在单个或分离的反应容器中直接氧化，从而获得酚，无需任何中间操作。更具体地，描述了一种通过Ir催化的芳烃硼化反应，使用二醇硼烷（HBPin）后，通过OXONE氧化中间芳基硼酸酯的过程。

  Iridium catalysed C−H borylation provides an effective method for late stage functionalization of fluorinated arenes and heteroarenes. The reaction occurs rapidly and efficiently with selectivity that can be best predicted using computed relative transition stage energies.
