A direct arylation to furnish diarylmethanes from benzyl alcohols was realized through Pd(PPh3)4-catalyzed Suzuki–Miyaura coupling via benzylic C–O activation in the absence of any additives. The arylation is compatible with various functional groups. This development provides an atom- and step-economic way to approach a diarylmethane scaffold under mild and environmentally benign conditions.
通过Pd(PPh3)4催化的Suzuki–Miyaura偶联反应,利用苯甲醇直接芳基化制备二芳基甲烷,通过对苄基C–O活化,无需任何添加剂。这种芳基化反应与多种官能团兼容。该研究开发了一种原子经济、步骤经济的方法,在温和环保的条件下制备二芳基甲烷骨架。
