Overview
Vinylferrocene is an organometallic compound combining a ferrocene moiety with a reactive vinyl group. It belongs to the family of ferrocene derivatives, known for their stability and electrochemical properties. The compound was first synthesized in the mid-20th century and has since become a versatile building block in materials science and catalysis. Its hybrid structure enables unique applications, bridging organic and inorganic chemistry. The vinyl group allows for polymerization or further functionalization, making it valuable for creating tailored materials. Industrial and academic demand stems from its redox activity and compatibility with diverse synthetic routes.
Physical and Chemical Properties
Vinylferrocene appears as orange-red crystals with a distinct metallic luster. It is stable under inert conditions but may degrade upon prolonged exposure to air or moisture. The compound exhibits moderate solubility in polar organic solvents like tetrahydrofuran (THF) but is insoluble in water due to its hydrophobic nature. Key chemical features include the iron-centered redox activity (Fe²⁺/Fe³⁺) and the vinyl group's reactivity toward electrophiles or radicals. Its melting point (51-53°C) is lower than unsubstituted ferrocene, reflecting the vinyl group's influence on crystal packing. Spectroscopic techniques (e.g., NMR, IR) confirm its structure, with characteristic signals for the cyclopentadienyl rings and vinyl protons.
Main Applications
In electrochemistry, vinylferrocene modifies electrodes to enhance electron transfer, useful in biosensors and energy storage devices. Its redox-active nature enables precise control over oxidation states, critical for catalytic cycles. The polymerizable vinyl group allows incorporation into conductive polymers, improving mechanical and electronic properties. These polymers find use in anti-static coatings, flexible electronics, and corrosion inhibitors. Biomedical researchers exploit its stability for drug-delivery systems or as a tracer in imaging studies. Additionally, it serves as a precursor for synthesizing complex ferrocene derivatives, which are applied in asymmetric catalysis and nonlinear optical materials.
Safety and Storage
Vinylferrocene is classified as an irritant, requiring handling in a fume hood with personal protective equipment (PPE) such as nitrile gloves and safety goggles. Avoid skin contact or inhalation of dust, which may cause respiratory or dermal irritation. Storage mandates airtight containers under inert gas (e.g., argon or nitrogen) to prevent oxidation. Refrigeration is recommended for long-term preservation, though the compound should be warmed to room temperature before opening to minimize condensation. Spills should be contained with inert absorbents and disposed of as hazardous waste, following local regulations.
B2B Procurement Guide
When sourcing vinylferrocene, prioritize suppliers with ISO certification or GMP compliance for chemical manufacturing. Key procurement criteria include purity (≥98%, verified by HPLC or NMR), batch consistency, and packaging (e.g., amber glass vials with septum seals). Bulk purchases (kilograms) may negotiate lower prices, but validate scalability of synthesis methods. Request safety data sheets (SDS) and technical notes detailing impurity profiles. For international shipments, confirm compliance with transportation regulations (e.g., IATA for air freight). Auditing supplier facilities for proper storage conditions ensures product integrity upon delivery.
