| Chemical Properties | (R,R)-(-)-N,N'-BIS(3,5-DI-TERT-BUTYLSALICYLIDENE)-1,2-CYCLOHEXANEDIAMINO-MANGANESE(III) CHLORIDE is Dark brown powder or chunks | | Uses | (R,R)-(-)-N,N'-BIS(3,5-DI-TERT-BUTYLSALICYLIDENE)-1,2-CYCLOHEXANEDIAMINO-MANGANESE(III) CHLORIDE is a coordinated compound of manganese and a salen-type ligand. It is also used as an asymmetric catalyst used to enantioselectively transform prochiral alkenes into epoxides. | | Uses | Chiral catalyst for epoxidation of olefins. | | Uses | Salen (Mn)-catalyzed asymmetric epoxidation of unfunctionalized olefins. High enantioselectivities and yields are obtained for a variety of substrates, especially cis-alkenes. A few applications include the synthesis of the taxol side chain and cis-1-amino-2-indanol. Jacobsen′s catalyst has also been used in the asymmetric α-hydroxylation of silyl enol ethers. Catalyst for the enantioselective epoxidation of a variety of olefins. | | Reactions |
- Catalyst for the conversion of olefins to chiral epoxides in high enantiomeric excess.
- Pharmaceutically important, single enantiomer amino alcohols are efficiently produced from the corresponding chiral epoxide by acid or base-catalyzed epoxide ring-opening reactions.
- symmetric Kinetic resolution of secondary alcohols in water.
- Enantioselective Reformatsky reaction with ketones.
