, p. 5363 - 5366 (2005)
A facile and efficient catalytic system of salicylaldimine-aluminum complexes for the ring-opening polymerization (ROP) of ε-caprolactone (CL) was investigated. The polymerization of Cl was examined at 25 °C in the presence of 1 mol % of benzyl alcohol (B

Excited-state intramolecular proton transfer involves a photochemical isomerization and creates the opportunity for the emission of two distinct wavelengths of light from a single fluorophore. The selectivity between these two wavelengths of emission is d
Comparative evaluation of antioxidant activity of 2-alkyl-4-methylphenols and their 6-n-octylaminomethyl derivatives
Buravlev,Fedorova,Shevchenko
, p. 985 - 992 (2019/06/17)
A series of 2-alkyl-4-methyl-6-n-octylaminomethylphenols (where alkyl is methyl or tert-butyl group, or terpene substituent) was synthesized. A comparative evaluation of the antioxidant properties of the starting alkyl- and terpenylphenols and their Mannich bases was carried out using in vitro assays. Structural features providing high antioxidant activity of these compounds were revealed.

Efficient microwave-assisted regioselective one pot direct: Ortho -formylation of phenol derivatives in the presence of nanocrystalline MgO as a solid base catalyst under solvent-free conditions
Naeimi, Hossein,Zakerzadeh, Elham
, p. 4590 - 4595 (2018/03/21)
In this research, at first nanocrystalline MgO was prepared and then the solvent-free reactions of phenol derivatives with paraformaldehyde in the presence of the obtained nanocrystalline MgO as a new catalyst under microwave irradiation were investigated. In this reaction, ortho-hydroxyaromatic aldehydes were yielded as products. This method seems to be comparable with other reported methods due to its high yield and regioselectivity. The significant features of this method are short reaction times, high yields, and easy and quick isolation of the products.
Solvent dependent disproportionation of Cu(II) complexes of N2O2-type ligands: Direct evidence of formation of phenoxyl radical: An experimental and computational study

Four Cu(II) complexes (1, 2, 3 and 4) with N2O2-type ligand, H2L1, H2L2, H2L3 and H2L4, respectively have been synthesized as the functional model for galactose oxidase. In presence of acetonitrile the Cu(II) centres in the complexes, undergo reduction with simultaneous oxidation of the ligands. The ligand oxidized products are isolated and characterized. Spectroscopic studies indicate that this disproportionation goes through the formation of a Cu(II)-phenoxyl intermediate. The complexes also undergoes the same reaction with pyridine, which indicates the involvement of the exergonic N-donor ligand for the formation of Cu(II)-phenoxyl complex. The Cu(II)-phenoxyl complexes are found to be stable in methanol in presence of a strong base. The paramagnetic centers in the Cu(II)-phenoxyl complexes were found to be weakly ferromagnetically coupled. The complexes, in acetonitrile solvent, have been found to oxidize primary alcohols to corresponding aldehydes. In absence of single crystal structures of the complexes, we optimized the structures using density functional theory (DFT). The UV-visible peaks of complexes as found from time dependent density functional theory (TDDFT) calculations match well with the observed experimental results.

A series of tridentate imine bis(phenolate) ligands have been synthesised and complexed to aluminium. Solid-state analysis identified two structural motifs of an aluminium dimer [Al2(Me)2(X)2]; one consisting of two five-c
Highly Enantioselective Epoxidation of α,β-Unsaturated Ketones Catalyzed by Rare-Earth Amides [(Me3Si)2N]3RE(μ-Cl)Li(THF)3 with Phenoxy-Functionalized Chiral Prolinols

A simple and efficient catalytic enantioselective epoxidation of α,β-unsaturated ketones has been successfully developed, which was catalyzed by rare-earth metal amides [(Me3Si)2N]3RE(μ-Cl)Li(THF)3 (RE = Yb (1), La (2), Sm (3), Y (4), Lu (5)) in the presence of phenoxy-functionalized chiral prolinols at room temperature using tert-butylhydroperoxide (TBHP) as the oxidant. The combination of an Yb-based amide 1 and a chiral proligand (S)-2,4-di-tert-butyl-6-((2-(hydroxydiphenylmethyl)pyrrolidin-1-yl)methyl)phenol) performed very well, and both the yields and the enantiomeric excess of the chiral epoxides reached up to 99% and 99% ee.
