Description
4-Bromo-2-iodopyridine is a heteroaryl halide featuring distinct bromo and iodo substituents at adjacent positions on the pyridine ring. This configuration enables selective cross-coupling reactions, particularly in palladium-catalyzed transformations, where the differing reactivities of the halogens facilitate sequential functionalization. The molecule exhibits excellent stability under standard conditions, enabling reliable use in complex synthetic sequences.
Application
4-Bromo-2-iodopyridine serves as a versatile dihalogenated pyridine building block for cross-coupling reactions, enabling efficient access to substituted heterocycles. Its orthogonal halogen reactivity facilitates sequential Pd-catalyzed couplings, with the bromo group typically undergoing reaction first. The compound exhibits good bench stability and is compatible with standard reaction conditions, simplifying purification and integration into complex molecular architectures.
