elucidated. TAEs have widespread applications in material science and supramolecular chemistry due to their aggregation‐induced emission (AIE) properties. The divergent and stereoselective synthesis of [3+1]‐, [2+2]‐, and [2+1+1]‐TAEs via multiple couplings of vinylboronates with aryl bromides is demonstrated. These couplings feature a broad substrate scope and excellent functional group compatibility
报道了新的四硼烷基乙烯(TBE)的合成,并阐明了其在制备[4 + 0]-四芳烃(TAE)中的应用。TAE由于其聚集诱导发射(AIE)特性而在材料科学和超分子化学中得到了广泛应用。通过乙烯基硼酸酯与芳基溴化物的多次偶联,证明了[3 + 1]-,[2 + 2]-和[2 + 1 + 1] -TAE的发散和立体选择性合成。由于温和的反应条件,这些偶联具有广泛的底物范围和出色的官能团相容性。提供了容易获得各种四芳烃的途径。该策略是对合成TAE的常规方法的重要补充,并且将是合成用于功能材料的基于TAE的分子的宝贵工具,
