Pyridine−borane complexes were synthesized from 2-arylpyridines through an electrophilic aromatic borylation reaction with BBr3. 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
吡啶-硼烷配合物是由2-芳基吡啶通过与BBr 3的亲电芳香化反应合成的。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,并用作各种取代的吡啶-硼烷络合物的合成平台。这种简便的方法对于合成具有硼-氮配位的氮杂-π-共轭材料将是有用的。
