Description

(Sp-5-13)-Chloro[2,2'-[1,2-Ethanediylbis[(Nitrilo-κn)Methylidyne]]Bis[4,6-Bis(1,1-Dimethylethyl)Phenolato-κo]]Manganese is a high-purity, organometallic manganese complex with a precisely defined chiral salen ligand structure. This compound matters as a highly effective and selective catalyst for a range of asymmetric organic transformations, enabling the synthesis of chiral intermediates with high enantiomeric purity. It is primarily needed by R&D chemists and process engineers in the pharmaceutical, agrochemical, and fine chemical industries for developing and scaling up advanced synthetic routes.

Application

• Asymmetric Epoxidation Catalyst: For the enantioselective epoxidation of unfunctionalized olefins, a key step in producing chiral epoxides.
• Pharmaceutical Intermediate Synthesis: Catalyzing critical asymmetric reactions in the manufacture of active pharmaceutical ingredients (APIs).
• Agrochemical Production: Used in the synthesis of enantiomerically pure herbicides, fungicides, and plant growth regulators.
• Fine Chemical Manufacturing: Enabling asymmetric C-H activation, cyclopropanation, and other C-C bond forming reactions.
• Academic & Industrial Research: A valuable tool for methodological development in organic synthesis and catalysis studies.
• Ligand Precursor: Can serve as a starting material for modifying or generating other chiral catalyst systems.
