Chemo-enzymatic cascade processes are invaluable due to their ability to rapidly construct high-value products from available feedstock chemicals. However, they have proven to be challenging because of the mutual inactivation of both catalysts. 499-40-1, Name is (2R,3S,4R,5R)-2,3,4,5-Tetrahydroxy-6-(((2S,3R,4S,5S,6R)-3,4,5-trihydroxy-6-(hydroxymethyl)tetrahydro-2H-pyran-2-yl)oxy)hexanal, molecular formula is C12H22O11. In a Article，once mentioned of 499-40-1, Quality Control of: (2R,3S,4R,5R)-2,3,4,5-Tetrahydroxy-6-(((2S,3R,4S,5S,6R)-3,4,5-trihydroxy-6-(hydroxymethyl)tetrahydro-2H-pyran-2-yl)oxy)hexanal
The crystal structures of three bis(dpyam)copper(II) complexes, [Cu(dpyam)2(NO2)](NO2) (I) and [Cu(dpyam) 2(O2CH)](ClO4) (II) and [Cu(dpyam) 2(ONO2)](BF4) (III) have been determined by X-ray analysis. In I, the copper atom and the asymmetrically bonded nitrito group lie on a crystallographic C2-axis. The nitrito group is clearly disordered about the C2-axis giving a square pyramidal cis-distorted octahedral (4+1+1*) chromophore rather than a pseudo-regular cis-distorted octahedral chromophore. In II and III, a distortion of the cis-distorted CuN4O2 chromophore towards a square pyramidal (4+1+1*) stereochemistry is also present. The polycrystalline EPR spectra of I-III together with the high asymmetry in geometry of the CuN4O2 chromophores are suggesting that all complexes appear to be near the static distortion limit of the fluxional CuN4O2 chromophore geometry. The electronic reflectance spectra of the three complexes involve two bands at the same intensity corresponding to a cis-distorted octahedral geometry.
