Manganese Pentacarbonyl Bromide Key Features

Carbonyl compound structure

Manganese pentacarbonyl bromide possesses five CO ligands, giving it excellent carbonyl coordination ability and transfer activity.

Clear crystal morphology

Compared to other manganese compounds with indeterminate morphologies, Mn(CO)5Br exists in crystalline form, which facilitates its accurate weighing, storage, and maintenance of compositional homogeneity during reactions.

Good solubility

This compound exhibits good solubility in a variety of organic solvents, facilitating its use under anhydrous and oxygen-free conditions.

Provides active manganese centers

It can serve as a source of active manganese for the preparation of other manganese complexes or as a precursor in specific catalytic cycles, playing a role in reactions such as ligand exchange and oxidative addition.

Manganese Pentacarbonyl Bromide Main Applications

Organometallic chemistry

In academic and research laboratories, Mn(CO)5Br is an important starting material for studying the reactivity of organomanganese compounds, synthesizing novel manganese complexes, and exploring novel catalytic reactions.

Catalytic reaction research

In catalytic hydrogenation, carbonylation, and organometallic synthesis, manganese pentacarbonyl bromide has been used as an active manganese source or transformation intermediate.

Pharmaceutical and chemical synthesis

This compound is mainly used as an intermediate in pharmaceutical and chemical synthesis, participating in the construction of active drug molecules or their intermediate structural units.

Fine chemicals production

Mn(CO)5Br can be used to synthesize certain fine chemicals, such as specialty dyes, photosensitive materials, or additives for polymer materials.

Materials science

It can be used to prepare metal-carbonyl derivatives or participate in the synthesis of metal nanostructures, making it suitable for exploring high-end functional materials.

Precautions

  1. Manganese pentacarbonyl bromide is sensitive to air and moisture, so it must be stored in a sealed environment under inert gas protection (such as argon or nitrogen). Low-temperature storage (0-6℃) is recommended, and it should be kept away from light and in a dry place.

  2. Operate in a fume hood, wearing protective gloves, protective glasses, and protective clothing to avoid inhaling dust or vapors.

  3. If the product comes into contact with skin or eyes, rinse immediately with plenty of water. If you feel unwell, seek medical attention immediately.

  4. Mn(CO)5Br is a manganese-containing metal carbonyl compound and should be managed and treated as heavy metal and organometallic chemical waste. It should not be discharged arbitrarily.

FAQ

1. What are the advantages of manganese pentacarbonyl bromide compared to Mn2(CO)10?

The former has a mononuclear structure with well-defined halide sites, making it easier to coordinate and subsequently modify or insert into reactions; while Mn2(CO)10, although commonly used, has slightly lower reactivity or controllability in some coordination systems due to its binuclear structure.


2. How to select Mn(CO)5Br in a catalytic system?

It can be used as a manganese-based catalytic precursor in anhydrous and organic solvent systems with ligands (such as phosphine ligands and amine ligands); a dry and inert environment must be maintained during operation.
