Author is Kwon, Mi-Ae; Kim, Geon-Joong.

The polymeric (salen) Co(III) catalysts containing various counter anions have been synthesized, and the asym. catalytic activities of these newly synthesized polymer-type salen complexes were investigated in the HKR of terminal epoxides. The polymeric chiral salen Co(III) complexes catalyze the hydrolysis of epichlorohydrin, 1,2-epoxybutane, 1,2-epoxyhexane and epoxystyrene with very high enantioselectivities under mild conditions. The catalysts could be recovered and reused several times without further treatment after reaction, showing no loss of activity and enantioselectivity.

In general, if the atoms that make up the ring contain heteroatoms, such rings become heterocycles, and organic compounds containing heterocycles are called heterocyclic compounds. An article called Spontaneous resolution among chiral glycerol derivatives: crystallization features of ortho-alkoxysubstituted phenyl glycerol ethers, published in 2007-08-22, which mentions a compound: 60827-45-4, Name is (2S)-(+)-3-Chloropropane-1,2-diol, Molecular C3H7ClO2, Computed Properties of C3H7ClO2.

Five chiral arylglycerol ethers 2-R-C6H4-O-CH2CH(OH)CH2OH (R = OMe, OEt, OPrn, OPri, OBut) have been prepared in racemic and enantiopure form. The m.ps. and enthalpies of fusion of every species were measured by differential scanning calorimetry. Binary phase diagrams were reconstructed for the whole family, the entropies of the mixing of the enantiomers in the liquid state, and Gibbs free energy of formation of the racemic compound, as well as Pettersson i-values were derived from the thermal data. The differences in the phase behavior of the investigated compounds were associated with the conformations of the alkoxy fragments.

The chemical properties of alicyclic heterocycles are similar to those of the corresponding chain compounds. Compound: 2-Methylglutaronitrile, is researched, Molecular C6H8N2, CAS is 4553-62-2, about Anodic Dissolution of Al Current Collectors in Unconventional Solvents for High Voltage Electrochemical Double-Layer Capacitors, the main research direction is anodic dissolution aluminum current collector solvent electrochem capacitor; capacitors; dissolution; electrolytes; high voltage; ion-solvent interactions.HPLC of Formula: 4553-62-2.

This study studied the anodic dissolution of Al current collectors in unconventional electrolytes for high voltage electrochem. double-layer capacitors (EDLCs) containing adiponitrile (ADN), 3-cyanopropionic acid Me ester (CPAME), 2-methyl-glutaronitrile (2-MGN) as solvent, and Et4N+ tetrafluoroborate (Et4NBF4) and Et4N+ bis(trifluoromethanesulfonyl)imide (Et4NTFSI) as conductive salts. To have a comparison with the state-of-the-art electrolytes, the same salts were also used in combination with MeCN (ACN). The chem.-phys. properties of the electrolytes were studied. Also, their impact on the anodic dissolution of Al was analyzed in detail as well as the influence of this process on the performance of high voltage EDLCs. The results of this study indicated that in the case of Et4NBF4-based electrolytes, the use of an alternative solvent is very beneficial for the realization of stable devices. When Et4NTFSI is used, the reduced solubility of the complex Al(TFSI)3 appears to be the key for the realization of advanced electrolytes.
