Half‐sandwich 18e rhodium iminophosphonamide complexes [Сp*RhCl(NPN)] with NPN = Ph2P(N‐p‐Tol)2 (1a), Ph2P(N‐p‐Tol)(NMe) (1b) and 16e cationic [Сp*Rh(NPN)](PF6) (2a+PF6‐) were found to catalyze transfer hydrogenation of carbonylic substrates (acyclic cyclic alkyl ketones, aromatic ketones aldehydes) the activity strongly enhanced by presence chloride ligand. Kinetic studies including KIE activation parameters measurements carried out for two model (acetophenone cyclohexanone) as well...
Abstract Mono‐ and dihomoallylamines serve as convenient precursors for the preparation of 6‐substituted piperidine‐2,4‐diones. This transformation is based, on one hand, a simple well‐known halocyclocarbamation reaction proceeding by addition source cationic halogen to N ‐Boc‐protected homoallylamines and, other, new enolate‐isocyanate rearrangement that proceeds action strong bases bromocyclocarbamates. A set racemic were prepared allylboration nitriles or primary amides with...
We expand the series of well-defined silica-supported titanium imido complexes general formula (≡SiO)Ti(═NtBu)X(py)n prepared via surface organometallic chemistry in order to analyze effect X ligand on their catalytic properties. Two new complexes, (≡SiO)Ti(═NtBu)Cl(py)2 (2s) and (≡SiO)Ti(═NtBu)Cp(py) (3s), have been characterized with physicochemical techniques, performance oxo/imido heterometathesis other imido-transfer reactions has studied compared that previously reported catalyst...
Abstract Hexanuclear rhodium carbonyl cluster, Rh 6 (CO) 16 , catalyzes benzene hydroxylation with hydrogen peroxide in acetonitrile solution. Phenol and (at lower concentration) quinone are formed the maximum attained total yield turnover number 17% 683, respectively. Certain other complexes, containing cyclopentadienyl ligands, 2 Cp 3 (CpMe) less efficient catalysts. Cyclopentadienyl derivatives of which do not contain Rh(CpMe 5 )(CH CH ) RhCp(cyclooctatetraene) (cyclooctatetraene) turned...
Photochemical properties of a series bifunctional monosubstituted derivatives cymantrene containing C-, N-, or O-bound π-allyl group, along with n-donating carbamate, amide, pyridine fragments were investigated. The results obtained demonstrate that the nature and thermodynamic stability cyclopentadienylmanganese dicarbonyl chelates derived from depend substantially on both functional groups their position in substituent at Cp ring. Thus, for six-membered chelates, increases carbamates <...
We report the first examples of catalytic oxo/imido heterometathesis reactions that involve carboxylic acid derivatives (lactones).
The synthesis of four new 1,2,3‐triazole derivatives and seven 1,2,3‐triazolium salts that contain an organometallic group (i.e., cymantrenyl ferrocenyl) at either the N‐1, N‐2, or N‐3 position was realized. alkylation organic triazole investigated, as a result these studies, it found presence good leaving heterocyclic nitrogen atom led to transalkylation subsequent migration N‐1 substituent N‐2 moiety. nucleophilicity counterion triazolium salt influenced isomerization processes, which...

Study resulting materials IR, solid‐state NMR, elemental mass balance analyses demonstrates that bis ‐ complex leads a predominant formation silica‐supported amide (≡SiO)Ti(NH from protonation ligand silanols...
High-temperature polymer-electrolyte membrane fuel cells (HT-PEMFCs) are a very important type of since they operate at 150-200 °C, making it possible to use hydrogen contaminated with CO. However, the need improve stability and other properties gas-diffusion electrodes still impedes their distribution. Self-supporting anodes based on carbon nanofibers (CNF) prepared using electrospinning method from polyacrylonitrile solution containing zirconium salt, followed by pyrolysis. After...
Abstract The chemical properties of chloro(dialkylamino)(diphenylphosphinoyl)methanes have been studied using the simplest compound this series, chloro(dimethylamino)(diphenylphosphinoyl)methane, as an example. Chloro(dimethylamino)(diphenylphosphinoyl)methane shows ambident reactivity when reacting with electrophiles and nucleophiles depending on coreactant nature, it behaves either electrophilic substrate or phosphorus nucleophile. This fact can be explained by its dissociation in...
Triallylborane–amines adducts are effective stoichiometric allylating agents in the aminoallylation reaction of carbonyl compounds methanol. Moreover, copper-catalyzed diastereoselective allylation Ellman's imine was achieved with triallylborane–methylamine adduct.
