it flow: An efficient and modular synthesis of biaryls under continuous‐flow conditions has been realized by a lithiation/borylation/Suzuki–Miyaura cross‐coupling sequence under ambient conditions. Aryl bromides and heteroaromatic precursors can be transformed in the room‐temperature lithiation reaction with nBuLi, followed by borylation and Suzuki–Miyauracoupling with the aid of ultrasonic irradiation
