Description

Cyclohexadienyliumiron(0) Tricarbonyl Tetrafluoroborate CAS NO 33678-01-2 is an organometallic salt complex featuring a cationic cyclohexadienyl-iron tricarbonyl moiety paired with a tetrafluoroborate anion. This compound serves as a versatile and valuable precursor in advanced synthetic chemistry, particularly for introducing the Fe(CO)3 unit into organic frameworks. It is primarily sought by research chemists and process development scientists in the pharmaceutical, agrochemical, and fine chemical industries for constructing complex molecular architectures.

Application

• Organometallic Synthesis: Acts as a key electrophilic source of the cationic (C6H7)Fe(CO)3+ synthon for the preparation of diverse iron-arene complexes.
• Catalysis Research: Employed as a precursor or catalyst component in exploratory reactions, including hydrogenation, isomerization, and carbonylation processes.
• Pharmaceutical Intermediate: Used in the research and development of novel active pharmaceutical ingredients (APIs) that incorporate organoiron motifs.
• Material Science: Investigated for the development of novel organometallic polymers, coatings, or materials with unique electronic properties.
• Asymmetric Synthesis: Utilized in the synthesis of chiral, non-racemic organoiron complexes for use in stereoselective transformations.
• Academic & Industrial R&D: A fundamental reagent for methodological studies in organometallic chemistry and reaction mechanism elucidation.

Quality Control

Our Cyclohexadienyliumiron(0) Tricarbonyl Tetrafluoroborate is produced and handled under strict quality protocols to ensure batch-to-batch consistency and reliability for sensitive synthetic applications. Each lot undergoes comprehensive analytical characterization, including NMR (1H, 13C, 11B, 19F), IR spectroscopy, and elemental analysis (CHN). A detailed Certificate of Analysis (COA) documenting purity, identity, and relevant physicochemical parameters is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C) under an inert atmosphere (e.g., argon or nitrogen) due to its sensitivity to oxidation and moisture. Keep the container tightly sealed in a desiccator to minimize exposure to atmospheric humidity. Isolate from strong bases and fluorides.
