Abstract [Fe(CO) 2 (SCH CH NH ) ] ( 1 , CORM‐S1), (SC 6 H 4 ‐2‐NH CORM‐S2), [Ru(CO) 3 ), and were prepared from the corresponding metal carbonyl compounds cysteamine (deprotonation of thiol functionality) or cystamine (oxidative addition S–S bond). They crystallized donor solvents, such as tetrahydrofuran dimethylformamide, adducts with bases bound by hydrogen bridges to amino functionalities. Although iron derivatives proved be valuable photosensitive CO‐releasing molecules (CORMs), CO was...
Several phenylthiolatomanganese carbonyl complexes of the type [(OC)4Mn(μ-SR)]2 (R = Ph (), C6H4-4-CH3 C6H4-4-CF3 C6H4-4-F C6H4-4-Cl C6H4-4-OMe C6F5 and CH2C6H4-4-Cl ()) have been prepared via reaction Mn2(CO)10 with diaryldisulfane or [(OC)5MnBr] arylthiols. These lose two carbon monoxide molecules quite easily yielding tetranuclear [(OC)3Mn(μ3-SR)]4 (). Derivatives fluoro-substituted aryl groups commonly form mixtures dinuclear which can quantitatively be converted to by heating...
Identifying and naming inorganic compounds is sometimes a challenge for many first-year chemistry engineering students; however, these difficulties can be overcome after extensive practice using homework sets based on or applying nomenclature rules. Werner card game in honor of Professor Alfred his great contributions to intended as didactic tool reinforcing the learning nomenclature. By playing game, students apply During they get identify such acids, bases, salts well systematic rules new...
Neurodegenerative diseases are characterized by increased permeability of the blood–brain barrier (BBB) due to alterations in cellular and structural components neurovascular unit, particularly association with neuroinflammation. A previous screening study peptide ligands identify molecular BBB neuroinflammation phage-display, revealed that phage clone 88 presented specific binding affinity endothelial cells under inflammatory conditions vivo vitro. Here, we aimed possible target receptor...
The reaction of N -phenyl-1-(pyridin-2-yl)methanimine with copper chloride dihydrate produced the title neutral complex, [CuCl 2 (C 12 H 10 )(H O)]·H O. Cu II ion is five-coordinated in a distorted square-pyramidal geometry, which two atoms bidentate Schiff base, as well one chloro and water molecule, form irregular base pyramidal structure. Meanwhile, apical ligand interacts through strong hydrogen bond molecule crystallization. In crystal, molecules are arranged pairs, forming stacking...
The mechanism and kinetic constants of the cascade cyclization involving vinyl, aryl N -alkoxyaminyl radicals for formation 1-azaspiro[4.4]nonanes.
Abstract A complete characterization of the vibrational modes has been performed for neutral and anionic pentafluorosulfur peroxides SF 5 OOX (X=H, F, Cl) structures using density functional theory (DFT). The adiabatic electron affinity, bond dissociation energy heat formation molecules were calculated several G n methods, starting from geometries optimized with B3LYP, M06‐2X MP2 levels theory. most accurate enthalpies at 298 K OOH, OOF, OOCl are obtained G4 level used as a reference. S−F...
