A small set of N,O‐chelated isoquinoline‐enol boron complexes featuring an aryl bromide functionality was prepared and employed in palladium‐catalyzed Suzuki couplings with arylboronic acids and bis(pinacolato)diboron. This allowed to obtain two new series of functionalized N,O‐chelated boron complexes and a novel type of bis‐fluorophore hybrid. The optical properties of all obtained complexes were assessed in solid state and in dichloromethane solution.
