5-溴-2-碘苯甲醛

5-Bromo-2-iodobenzaldehyde is a useful synthetic intermediate. It is used to prepare aza-fused polycyclic quinolines via copper-catalyzed cascade intermolecular condensation. It is also used in the synthesis of oxoindenopyrroles via copper-catalyzed tandem cycloaddition and coupling of iodoarylynones with isocyanides.
