The important role of (R)-[1,1′-Binaphthalene]-2,2′-diamine

Because enzymes can increase reaction rates by enormous factors and tend to be very specific, Recommanded Product: (R)-[1,1′-Binaphthalene]-2,2′-diamine, typically producing only a single product in quantitative yield, they are the focus of active research.you can also check out more blogs about 18741-85-0

Chemistry is the experimental and theoretical study of materials on their properties at both the macroscopic and microscopic levels.In a patent， Recommanded Product: (R)-[1,1′-Binaphthalene]-2,2′-diamine, Which mentioned a new discovery about 18741-85-0

The enantiopure Ni(II) helicates [Ni2L1RR.Cl2] (1), [Ni2L1SS.Cl2] (1?), [Ni2L2RR.Cl2] (2), [Ni2L2SS.Cl2] (2?) were synthesized by one-pot self-assembly technique from R-(+)- or S-(?)-1,1?-binaphthyl-2,2?-diamine, with 4-methyl-2,6-diformyl phenol or 4-tert-butyl-2,6-diformyl phenol and nickel salts. This binuclear double stranded Ni(II) helicates were characterized by ESI-MS, IR and single crystal X-ray structure wherever applicable. The extensive chiroptical studies suggest that the complexes are enantiopure in nature. The chirality transfer from ligand L1RR & L2RR to Ni(II) metal centre produced DeltaDelta geometrical chirality, while their enantiomeric counterpart L1SS & L2SS produced LambdaLambda chirality in their respective complexes.These enantiopure helicates were applied as catalysts in asymmetric Michael addition of 1,3-dicarbonyl compounds with beta-nitrostyrene to produce nitroalkanes in good yield (96?98%) and ee (78?94%). (Figure presented.).
