Description

TCI D4858 4,6-Dibromodibenzofuran is a heterocyclic building block constructed on the dibenzofuran framework — two benzene rings joined through a fused furan ring — carrying two bromine atoms at the 4 and 6 positions. This TCI product plays an important role in the laboratory as a starting point for the synthesis of larger molecules built around a rigid scaffold. The two bromine groups are arranged symmetrically on either side of the oxygen bridge, which makes the compound a bifunctional material: researchers can attach two different groups or two identical groups through cross-coupling reactions, so the synthesis of large target molecules becomes considerably more concise.

The key characteristics behind its selection are the dibenzofuran framework itself, which is rigid, planar, and thermally stable, combined with the reactivity of the carbon–bromine bonds, which are readily activated by palladium catalysts. The C–Br bonds at the 4 and 6 positions sit adjacent to the bridging oxygen atom, so these positions are frequently exploited to build bidentate ligands as well as structures with a specific angular geometry. Dibenzofuran is also known for its wide energy gap and good stability, which is why it is widely used as a core group in host materials for devices.

In Indonesian laboratories, this building block is typically used in synthetic organic chemistry and materials chemistry research groups, where it serves as the scaffold from which more elaborate target structures are assembled. It is drawn on for cross-coupling work on the laboratory bench, for preparing ligand precursors, and for exploratory studies on rigid aromatic cores. Because it is supplied as a defined TCI catalogue item under a single CAS number, it fits routine research use where a consistent, well-identified starting material is required across repeated experimental runs.

Laboratory Applications

Palladium-catalysed cross-coupling synthesis — the two C–Br bonds are readily activated by palladium catalysts, allowing controlled attachment of aryl or heteroaryl fragments onto the dibenzofuran core.
Bifunctional double functionalisation — the symmetrical 4,6-bromine arrangement lets researchers install either two identical groups or two different groups, shortening multi-step routes to large target molecules.
Bidentate ligand preparation — because both C–Br positions sit adjacent to the bridging oxygen atom, they are frequently used to construct bidentate ligand frameworks with defined donor spacing.
Angular and rigid scaffold construction — the planar, rigid dibenzofuran framework gives a fixed geometry, making it suitable for building target structures that require a specific angular arrangement.
Host material core synthesis — dibenzofuran's wide energy gap and good stability make this building block a common starting point for core groups in host materials for devices.

Handling and Storage

Store 4,6-Dibromodibenzofuran in its original tightly closed container in a cool, dry, well-ventilated area, away from direct sunlight, moisture, and sources of heat or ignition. Amber glass or the supplier's original packaging is suitable for keeping the material protected from light; keep the container sealed between uses to limit exposure to atmospheric moisture. Handle the solid in a fume hood or a well-ventilated workspace, and weigh it carefully to avoid generating dust. Standard laboratory personal protective equipment — safety glasses, chemical-resistant gloves, and a laboratory coat — should be worn during handling. Avoid contact with skin and eyes and avoid inhaling any dust. Consult the manufacturer's Safety Data Sheet before use, and dispose of residues and contaminated materials in accordance with your institution's chemical waste procedures and applicable local regulations.
