Continuous‐Flow Synthesis of Biaryls Enabled by Multistep Solid‐Handling in a Lithiation/Borylation/Suzuki–Miyaura Cross‐Coupling Sequence

Abstract

Let 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–Miyaura coupling with the aid of ultrasonic irradiation (see scheme).
