Pyridine-borane complexes were synthesized from 2-arylpyridines through an electrophilic aromatic borylation reaction with BBr(3). The intermediate 2-(2-dibromoborylaryl)pyridines were stable enough to be handled in air and served as the synthetic platform for variously substituted pyridine-borane complexes. This facile method would be useful for the synthesis of aza-π-conjugated materials having boron-nitrogen coordination.
通过三溴化硼（BBr(3)）的亲电芳香硼酸化反应，从 2-芳基吡啶合成了吡啶硼烷配合物。中间体 2-(2-二溴硼基芳基)吡啶足够稳定，可以在空气中处理，并且可用作各种取代的吡啶硼烷配合物的合成平台。这种简便的方法将有助于合成具有硼-氮配位的氮杂-π 共轭材料。
