Description

Platinum, [1,1'-(1,4-Butanediyl)bis[1,1-diphenylphosphine-κP]]dichloro-, (Sp-4-2)- is a high-value, air-sensitive organometallic complex featuring a chelating diphosphine ligand, widely recognized as a highly effective homogeneous catalyst precursor. Its significance lies in its ability to facilitate a range of critical chemical transformations with excellent selectivity and activity under mild conditions. This compound is essential for R&D chemists and process engineers in the pharmaceutical, fine chemical, and advanced materials sectors seeking efficient catalytic solutions.

Application

• Hydrogenation Catalyst: A key precursor for the selective hydrogenation of alkenes, alkynes, and functionalized substrates in pharmaceutical intermediate synthesis.
• Hydrosilylation Reactions: Employed in the catalytic addition of silicon-hydrogen bonds across unsaturated carbon-carbon bonds for silicone polymer production and surface treatments.
• Cross-Coupling Catalysis: Serves as a catalyst precursor in C-C and C-X bond-forming reactions, such as Heck, Suzuki, and Stille couplings.
• Asymmetric Synthesis: The chiral, chelating phosphine ligand framework makes it valuable for developing enantioselective catalytic processes.
• Fine Chemical Manufacturing: Used in the production of complex molecules, including fragrances, agrochemicals, and specialty polymers.
• Academic & Industrial R&D: A fundamental tool for investigating new catalytic cycles and developing novel synthetic methodologies.
• Material Science: Potential applications in the deposition of platinum-containing thin films or nanomaterials.

Quality Control

Our organometallic catalysts are manufactured under controlled conditions to ensure batch-to-batch consistency and high catalytic performance. Each lot undergoes rigorous analytical testing, including NMR, elemental analysis (CHN), and HPLC, to verify identity, purity, and the absence of deleterious impurities. A comprehensive Certificate of Analysis (COA) detailing all specifications is provided with every shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Due to its sensitivity to oxygen and moisture, this material should be stored under an inert atmosphere (argon or nitrogen) in a cool, dry place. Recommended long-term storage temperature is 2-8°C. Allow the sealed container to equilibrate to room temperature before opening to prevent condensation.
