An efficient visible light induced rhodium(I)-catalyzed regioselective borylation of aromatic C-H bonds is reported. The photocatalytic system based on a single NHC-RhI complex capable both harvesting and enabling the bond breaking/forming at room temperature. chelating nature NHC-carboxylate ligand was critical to ensure stability RhI provide excellent activities. Experimental mechanistic studies evidenced photooxidative ortho addition upon irradiation with blue LEDs, leading cyclometalated RhIII -hydride intermediate.

This article defines the role that continuous flow chemistry can have in new reaction discovery, thereby creating molecular assembly opportunities beyond our current capabilities. Most notably focus is based upon photochemical, electrochemical and temperature sensitive processes where methods machine assisted processing significant impact on chemical reactivity patterns. These platforms are ideally placed to exploit future innovation data acquisition, feed-back control through artificial intelligence (AI) learning (ML) techniques.
