Description

(T-4)-[2,2'-[(1R,2R)-1,2-Cyclohexanediylbis[(Nitrilo-κn)Methylidyne]]Bis[4,6-Bis(1,1-Dimethylethyl)Phenolato-κo]]Zinc is a sophisticated organometallic complex featuring a chiral salen-type ligand, designed for high-performance catalytic applications. This compound matters because it offers exceptional stereoselectivity and thermal stability, making it a superior catalyst for asymmetric synthesis and polymerization reactions. It is primarily needed by R&D chemists and process engineers in the pharmaceutical, fine chemical, and advanced polymer industries seeking to develop novel, high-value products with precise molecular control.

Application

• Asymmetric Catalysis: A key chiral catalyst for enantioselective organic transformations, including epoxidation, cyclopropanation, and Diels-Alder reactions.
• Polymerization Initiator: Used as a single-site catalyst for the controlled polymerization of lactones, epoxides, and other monomers to produce polymers with specific tacticity and molecular weight.
• Pharmaceutical Intermediate Synthesis: Enables the production of chiral drug intermediates and active pharmaceutical ingredients (APIs) with high enantiomeric excess (ee).
• Material Science Research: Employed in developing novel coordination polymers and metal-organic frameworks (MOFs) with tailored properties.
• Ligand Precursor: Serves as a precursor for generating other metal complexes by transmetalation or ligand exchange reactions.
• Academic & Industrial R&D: A valuable tool for methodological development in synthetic organic and organometallic chemistry.
