Description

([2S,3S]-Bis[Diphenylphosphino]Butane)(Eta3-Allyl) Palladium(II) Perchlorate CAS NO 95070-72-7 is a highly specialized, chiral organometallic catalyst complex. This compound matters for its exceptional stereoselectivity in asymmetric synthesis, enabling the production of enantiomerically pure intermediates critical for advanced pharmaceuticals and fine chemicals. It is primarily needed by R&D chemists and process development teams in the pharmaceutical, agrochemical, and advanced materials sectors seeking efficient and selective cross-coupling and allylic substitution reactions.

Application

• Asymmetric Catalysis: A key chiral ligand-metal complex for enantioselective C-C and C-X bond-forming reactions.
• Pharmaceutical Intermediate Synthesis: For the stereocontrolled construction of chiral centers in active pharmaceutical ingredients (APIs).
• Fine Chemical Production: Enables the synthesis of complex, high-value organic molecules with defined stereochemistry.
• Cross-Coupling Reactions: Catalyzes reactions such as asymmetric allylic alkylations (AAA) and related transformations.
• Academic & Industrial R&D: A valuable tool for methodological development in synthetic organic and organometallic chemistry.
• Agrochemical Synthesis: Used in the development of chiral pesticides and herbicides.
