Product Description

Product Description

(S,S)-(+)-N,N'-Bis(3,5-di-tert-butylsalicylidene)-1,2-Cyclohexanediamino-Cobalt(II) is a chiral cobalt complex characterized by the coordination of a cobalt (II) ion with two ligands derived from 3,5-di-tert-butylsalicylaldehyde and 1,2-cyclohexanediamine. The compound exhibits a chelate structure and is known for its chiral properties, existing as two enantiomers. It finds applications in coordination chemistry and catalysis, particularly in asymmetric catalytic reactions. The compound's steric hindrance, strong coordination bond, and chiral nature contribute to its unique properties and potential use in various research fields.

Fetures

1. Chiral nature: The compound is chiral, meaning it exists as two enantiomers, designated as (S,S)- and (R,R)-, based on the arrangement of the ligands around the central cobalt ion. This chiral property can have implications in terms of its behavior in chemical reactions and interactions with other molecules.

2. Ligand coordination: The compound features coordination of the cobalt (II) ion with two ligands derived from 3,5-di-tert-butylsalicylaldehyde and 1,2-cyclohexanediamine. This coordination results in the formation of a chelate structure.

3. Strong coordination bond: The coordination bond between the cobalt ion and the ligands is typically strong, contributing to the stability and structure of the compound.

4. Steric hindrance: The bulky tert-butyl groups in the ligands create steric hindrance, which can influence the reactivity and properties of the compound.

5. Potential catalytic applications: Cobalt complexes, including this compound, have been investigated for their potential catalytic activity in various chemical reactions. The chiral nature of the compound can make it suitable for asymmetric catalysis, where it can selectively produce specific enantiomers of a target molecule.

Applications

1.
Catalyst used in the kinetic resolution of racemic, terminal epoxides yielding a chiral diol and the unreacted enantiomer of the epoxide.

2.
Precursor to a Co(III) catalyst for the kinetic resolution of terminal epoxides with alcohols.

3.
Desymmetrization of meso-epoxides with carboxylic acids and fluoride.

4.
Catalyst for asymmetric cyclopropanation of styrene.

5.
Catalyst for copolymerization of CO2 and epoxides.

6.
Enantioselective intramolecular openings of oxetanes. Chiral chemicals, Chiral catalyst Jacobsen Metal, (S,S)-Salen-Co, S,S-jacobsen Catalyst.
