Molecular hosts capable of chiroptical sensing of complexed guest molecules offer an attractive alternative to conventional methods for the analysis of the absolute configuration and enantiopurity. Sensors based on the Pfeiffer effect rely on complexation-driven asymmetric transformation of the first kind and can produce a chiroptical signal against an otherwise null background. To be most effective, the wavelength of the induced chiroptical sensor readout should be free and clear of interfering signals coming from the sample under investigation. In this study, we report the introduction of stereodynamic zinc complexes of antenna biphenols, a new class of sensors bearing antenna-like appendages that can extend the wavelength of the chiroptical signal while also improving enantioselective guest recognition.

Racemic trans -cyclohexane-1,2-diamine was allowed to react with eleven aldehydes with different patterns of substitution at the aromatic ring, in the absence of solvent, by manually milling the reagents. The corresponding imines were obtained in moderated to high chemical yields, in only 10 minutes of reaction. A one-pot, two-step preparation of stable complexes of selected imines with Pd(OAc) 2 and Cu(OAc) 2 and the use of these complexes as catalysts in the aromatization of methyl 1-oxo-1,2,3,4-tetrahydronaphthalene-2-carboxylate to the corresponding methyl 1-hydroxynaphthalene-2-carboxylates, is also reported.

The development of a new tetraamine-iron complex as a catalyst for the cyclization of propylene oxide with carbon dioxide to form propylene carbonate is reported. The structure of the complex was confirmed by X-ray crystallography. The molecule exhibited an exceptionally long iron-chlorine bond and a high catalytic activity even without the addition of an activator. However, kinetic studies showed a second-order dependence on catalyst concentration. By using iron, we provide an ecologically as well as economically favourable alternative to the preferentially used toxic metals cobalt and chromium. On the basis of the kinetics and other experimental data, the catalytic cycle deduced as well as an understanding of the high activities. Carbon dioxide can be used as a C1 feedstock in several reactions. The iron compound presented herein catalyses the cyclization of epoxides with CO2. The iron-basedcatalyst represents an economic and ecological alternative to commonly used cobalt or aluminium compounds. Copyright

Science experiments are a great way to spark their curiosity, get their minds active, and encourage them to do something that doesn’t involve a screen. 33100-27-5, C10H20O5. A document type is Article, introducing its new discovery.

The complex formation between different crown ethers and the cryptand [222] with alkali metal and ammonium ions in chloroform has been investigated by means of calorimetric titrations. The stability constants, reaction enthalpies and entropies for complex formation in chloroform have been determined. The complexation of alkali metal ions is favored by enthalpic contributions and influenced by both the ligand and the nature of the cation. The reaction enthalpies for complex formation of different ammonium salts with cryptand [222] are higher compared to the corresponding values for the reaction with different 18-crown-6 derivatives in chloroform due to the complete encapsulation of ammonium ion by the cryptand [222]. The benzo group attached to the crown ethers and the nature of the anion borne by the ammonium ion influence complex formation of ammonium with crown ethers. In the case of ammonium salts, competitive measurements have been carried out to underline the influence of the anion upon the complex formation. From the reaction enthalpies for complexation of ammonium ions, the contributions for the formation of hydrogen bonds are calculated using experimental data.

33100-27-5, Name is 1,4,7,10,13-Pentaoxacyclopentadecane, molecular formula is C10H20O5, belongs to chiral-catalyst compound, is a common compound. In a patnet, once mentioned the new application about 33100-27-5, COA of Formula: C10H20O5

Rate enhancements for the reduction of dioxygen by a MnII complex were observed in the presence of redox-inactive group 2 metal ions. The rate changes were correlated with an increase in the Lewis acidity of the group 2 metal ions. These studies led to the isolation of heterobimetallic complexes containing MnIII-(mu-OH)-MII cores (MII = CaII, BaII) in which the hydroxo oxygen atom is derived from O2. This type of core structure has relevance to the oxygen-evolving complex within photosystem II.

Lithium-7 NMR spectrometry was used to study the complexation reaction between lithium ions and several 12-, 15- and 18-membered crown ethers in a number of binary acetonitrile-nitrobenzene mixtures. Formation constants of the resulting 1:1 complexes in different solvent mixtures were determined by computer fitting of the chemical shift-mole ratio data. There is an inverse relationship between the complex stability and the amount of acetonitrile in the mixed solvent. Among different sized crown ethers used, 15-crowns were found to form the most stable Li+ complexes in the series. The influence of substitution on the macrocyclic rings on the stability of the resulting complexes is discussed.
