Herein we report the first FeII-catalyzed aerobic biomimetic oxidation of amines. This reaction involves several electron transfer steps and is inspired by biological in respiratory chain. The from amine to molecular oxygen aided two coupled catalytic redox systems, which lower energy barrier improve selectivity reaction. An iron hydrogen complex was utilized as substrate-selective dehydrogenat...
In this second paper in the series, we carefully analyze observational properties of optical FeII and NIR CaII triplet Active Galactic Nuclei, as well luminosity, black hole mass, Eddington ratio order to define driving mechanism behind our sample. The shows an inverse Baldwin effect, bringing out particular behavior ion with respect other low-ionization lines such H$\beta$. We performed a Prin...
The C-8 position of deoxyguanosine (dGuo) was hydroxylated by ascorbic acid in the presence of oxygen (O2) in 0.1 M phosphate buffer (pH 6.8) at 37 degrees C. Addition of hydrogen peroxide (H2O2) remarkably enhanced this hydroxylation. The Udenfriend system [ascorbic acid, FeII, ethylenediaminetetraacetic acid (EDTA) and O2] was also effective for hydroxylation of dGuo in high yield. Guanine re...
The linear, two-coordinate and isostructural heteroleptic [M(IPr){N(SiMe3)2}] (IPr = 1,3-bis(diisopropylphenyl)-imidazol-2-ylidene), formally MI complexes (M = Co, 3; Fe, 4) were obtained by the reduction of [M(IPr)Cl{N(SiMe3)2}] with KC8, or [Co(IPr){N(SiMe3)2}2] with mes*PH2, mes* = 2,4,6-tBu3C6H2. The magnetism of 3 and 4 implies CoII and FeII centres coupled to one ligand-delocalized electr...
We present 2 ′′ to 7 ′′ resolution 3 mm continuum and CO(J=1−0) line emission and near infrared K s , H 2 , and [FeII] images toward the massive star forming region W75 N. The CO emission uncovers a complex morphology of multiple, overlapping outflows. A total flow mass of > 255 M ⊙ extends 3 pc from end-to-end and is being driven by at least four late to early-B protostars. More than 10% of th...
