Description

[[Bis(Pentafluorophenyl)Phosphino]Ethynyl]Diphenylphosphine is a sophisticated organophosphorus ligand featuring a unique ethynyl-bridged bisphosphine structure with electron-withdrawing pentafluorophenyl groups. This compound matters for its exceptional ability to modulate the electronic and steric properties of transition metal catalysts, enabling highly selective and efficient catalytic transformations. It is primarily needed by researchers and process chemists in the pharmaceutical, agrochemical, and advanced materials sectors for developing novel synthetic methodologies and fine chemical production.

Application

• Homogeneous Catalysis: As a specialized ligand for cross-coupling reactions (e.g., Suzuki, Heck, Sonogashira), hydrogenation, and hydroformylation.
• Pharmaceutical Intermediate Synthesis: Enabling key carbon-carbon and carbon-heteroatom bond-forming steps in the synthesis of complex drug molecules.
• Advanced Material Development: For the creation of novel metal-organic frameworks (MOFs) and organometallic polymers with tailored properties.
• Agrochemical Research: In the development of new active ingredients requiring precise stereochemical control.
• Asymmetric Synthesis: Potential use in designing chiral catalysts for the production of enantiomerically pure compounds.
• Academic & Industrial R&D: A valuable tool for investigating new catalytic cycles and reaction mechanisms in organometallic chemistry.

Quality Control

Our [[Bis(Pentafluorophenyl)Phosphino]Ethynyl]Diphenylphosphine is manufactured under strict quality protocols to ensure batch-to-batch consistency and high purity for research and development applications. Each lot is characterized using advanced analytical techniques, including NMR (1H, 13C, 31P) and HPLC. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and assay is provided with every shipment to support your quality assurance requirements.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (argon or nitrogen) at 2-8°C in a cool, dry, and well-ventilated place. Due to its sensitivity to oxidation and moisture, the container should be purged with inert gas after each opening to maintain product integrity.
