Description

Platinum, Bis(Phenylethynyl)Bis(Triphenylphosphine)-, (Sp-4-1)- is a highly specialized organometallic complex featuring a square-planar platinum(II) center coordinated by two phenylethynyl ligands and two triphenylphosphine ligands. This compound matters as a versatile and efficient catalyst precursor, particularly valued for its role in facilitating cross-coupling and hydrosilylation reactions critical for advanced material synthesis. It is primarily needed by R&D chemists and process engineers in the pharmaceutical, agrochemical, and specialty polymer industries for developing novel compounds and high-performance materials.

Application

• Catalyst for Cross-Coupling Reactions: A key precursor for Sonogashira, Heck, and related C-C bond forming reactions in fine chemical and pharmaceutical intermediate synthesis.
• Hydrosilylation Catalyst: Used to catalyze the addition of silicon-hydrogen bonds across unsaturated organic compounds for producing silicone polymers and functional silanes.
• Material Science Research: Employed in the development of novel organometallic frameworks, molecular wires, and conductive polymers due to its defined structure and reactivity.
• Organic Light-Emitting Diodes (OLEDs): Serves as a potential component or synthetic intermediate in the creation of phosphorescent emitters and electron-transport materials.
• Laboratory Reagent: Used as a standardized, high-purity reagent for methodological development and mechanistic studies in academic and industrial research settings.
