    manganese(III) complexes show grossly identical features consisting of a reversible or quasireversible Mn III /Mn II reduction. Besides Mn III /Mn II reduction, the complexes 4 , 5 , 10 , 13 and 16 also show reversible or quasireversible Mn III /Mn IV oxidation. A linear correlation has been found for the complexes 5 , 7 , 11 and 13 [Mn(L 2 )(X)(H 2 O)] (X = F, Cl, Br, I) when E 1/2 [Mn III /Mn II ] is

    oxidation state of the manganese ions in these complexes is +IV. The electronic spectra show an intense band around 16000 cm−1 which can be assigned to a charge-transfer transition. In the cyclic voltammograms, two cathodic waves are observed at half-peak potentials around +0.9 V and −0.2 V(vs. SCE); they can be assigned to the reductions of Mn(IV) to Mn(III) and of Mn(III) to Mn(II) respectiv...

  • Facile, Efficient, and Diastereoselective Synthesis of Heterohelicene-like Molecules
    作者:Wei Lin、Guo-Lan Dou、Ming-Hua Hu、Cheng-Pao Cao、Zhi-Bin Huang、Da-Qing Shi

    日期:2013.3.15
    A concise and efficient route to new and interesting heterohelicene-like molecules has been developed through the one-pot, cascade reductive coupling reaction of o-hydroxydiimines or o-nitrodiimines and triphosgene in the presence of TiCl4/Sm. Purification of the final products only required a single recrystallization leading to high purity. High diastereoselectivity was also achieved, and two structures of the final products were confirmed by X-ray diffraction analysis.

  • Vanadyl tetradentate Schiff base complexes as catalyst for C–H bond activation of olefins with tert-butylhydroperoxide: Synthesis, characterization and structure
    作者:Saeed Rayati、Niloofar Torabi、Akbar Ghaemi、Sajjad Mohebbi、Andrzej Wojtczak、Anna Kozakiewicz

    Three N2O2 tetradentate Schiff base ligands (H2L1-3) were prepared by reaction of 1,2-propylenediamine and appropriate aldehyde and ketone and characterized by FT-IR, H-1 and C-13 NMR. The vanadyl complexes were synthesized by treating an ethanolic solution of the appropriate ligand and one equivalent of VO(acac)(2) to yield VOL1-3. These oxovanadium (IV) complexes were characterized on the basis of their FT-IR, UV-Vis spectroscopy and elemental analysis. The crystal structure of VOL3 has been determined. The metal center in VOL3 is a deformed tetragonal pyramidal N2O3 coordination sphere. These complexes are used as catalyst for the selective epoxidation of olefins. High selectivity of epoxidation for cyclooctene observed from oxidation data. The catalytic activity increases as the number of electron-donor groups increases, and the catalytic selectivity is varied by changing the substituents on the ligands. The catalytic system described here is an efficient and inexpensive method for the oxidation of olefins, with the advantages of high activity, selectivity, re-usability and short reaction time.
