A novel oxidative cross-coupling of benzo[b]thiophene 1,1-dioxides with arylboronic acids was reported. The efficient reaction occurred at the C2-position via C–H activation, followed by Pd(II)-catalyzed arylation. Furthermore, a series of C2-arylated products with significant photoluminescence properties have been synthesized and characterized, which illustrates the potential applications of our method in the aggregation-induced emission field.

钯催化苯并[b]噻吩 1,1-二氧化物与芳基硼酸的 C2 选择性直接芳基化

报道了苯并[ b ]噻吩1,1-二氧化物与芳基硼酸的新型氧化交叉偶联。通过 C-H 激活，有效的反应发生在 C2 位，然后是 Pd(II) 催化的芳基化。此外，还合成并表征了一系列具有显着光致发光特性的C2-芳基化产物，这说明了我们的方法在聚集诱导发射领域的潜在应用。
