Currently, the chemistry of organofluorine compounds is a leading and rapidly developing area organic chemistry. Fluorine present in molecule largely determines its specific chemical biological properties. This thematic issue covers trends that have been actively developed Russia last 15 – 20 years. The review describes nucleophilic substitution heterocyclization reactions involving fluorinated arenes quinones skeletal cationoid rearrangements polyfluoroarene series. transformations CF 3...
The NBS‐induced reaction of camphene with sulfonamides in acetonitrile the presence cesium carbonate and three‐fold excess NBS results formation Ritter type solvent interception products spiro‐joined imidazoline ring unrearranged framework (major products, up to 70%), rearranged fused azetidine rings (minor 28%). With equimolar amount NBS, only quinazoline tetrahydropyrimidine are formed 74% yield. derivatives monoterpenes represent practically unknown class compounds, their structure was...
A gas-phase electron diffraction analysis combined with mass-spectrometry (GED/MS) of (2R,9S)-trans-2,9-diiodo-13-(triflyl)-13-azabicyclo[8.2.1]tridec-5-ene was performed and the results were compared those studied earlier by GED/MS X-ray triflamide derivatives, that is 3,7,9-tris(triflyl)-3,7,9-triazabicyclo[3.3.1]nonane, 6-iodo-3-(triflamidomethyl)-4-triflyl-1,4,2,7-oxazadisilepane, 2,2,4,4-tetramethyl-6,8-bis(triflyl)-3-oxa-6,8-diaza-2,4-disilabicyclo[3.2.2]nonane. In addition, first GED...
The review covers the electrochemical reactions of oxygen reduction (ORR) and carbon dioxide (CO<sub>2</sub>RR) with a focus on mechanisms, structure intermediates, thermodynamics reactions. ORR metal,heteroatom-codoped nanocarbon substrates as catalysts is promising source pure electrical energy. CO<sub>2</sub>RR, being synthetic analogue photosynthesis reaction, has great potential for generation partial or complete products. Theoretical insights into mechanism...
The present state of research into reactions involving bimolecular nucleophilic substitution at a vinyl centre is examined. Attention concentrated on stereochemical questions and also the influence various details molecular structure reacting compound kinetics mechanism reactions. bibliography includes 167 references.
NBS-induced oxidative sulfamidation of trimethyl(vinyl)silane is strongly solvent and reagent dependent leading to various heterocycles in up quantitative yield.
Single Si-doped graphene C53H18Si with one carbon atom replaced by a three-coordinate silicon is studied density functional theory (DFT) calculations as catalyst for the oxygen reduction reactions (ORRs) in both acidic and alkaline media. The active sites adsorption were determined from distribution of charge difference analysis. At equilibrium electrode potential, most stable intermediate was found to have structure HO*O*-C53H18Si atoms bound support, them being incorporated between Si C...
Data on the imine–enamine and related types of tautomerism are surveyed different approaches to problems enamides, which play a major role in biological processes, examined. The bibliography includes 98 references.
The structures of pyrrolylmethylidene derivatives 2,3-dihydro-1H-inden-1-one (3), 3,4-dihydro-naphthalen-1(2H)-one (4), and cycloalkanones (5-7) were studied for the first time in solid state solution by NMR, IR, UV spectroscopies supported DFT quantum mechanical calculations. It was shown that all compounds except cycloheptanone derivative 7 both crystal exist form dimers where single E or E,E configuration with respect to exocyclic C═C bond is stabilized intermolecular hydrogen bonds...
Abstract An intriguing question in the general problem of aromaticity is whether captodative aromatic systems with donor and acceptor substituents at same carbon CC bond can be more stable than π‐conjugated push‐pull counterparts? The analysis electronic, magnetic, structural criteria showed that for conventional organic XO, TfN, (NC) 2 C, (NO ) Tf tropylidene derivatives [tropylium] + CHCHX − are expectedly their isomers C(X )CH , lowest Δ E most strong C. A different behavior...
Vinylogs of fulvalenes with cyclopropenyl and cyclopentadienyl moieties attached either to different carbon atoms ( c-C 3H 2CHCHC 5H 4- c, 7) or the same atom [XC( 2)( 4), 10] [X = CH 2; C(CN) C(NH 2) C(OCH O; 4; SiH CCl 2] double bond inserted between two rings are examined theoretically at B3LYP/6-311G(d,p) level. Both types compounds shown possess aromaticity, which was called "push-pull" "captodative" respectively. For captodative mesoionic structures XC( presence both aromatic CC is...
Abstract 2‐(Pyrrol‐2‐ylmethylene)‐1,3‐indandione ( 4 ) and 2‐(pyrrol‐2‐ylmethylene)‐3‐dicyanomethylidene‐1‐indanone 5 were synthesized. Multinuclear 2D‐NMR, IR, UV spectroscopic investigations as well quantum chemical calculations showed the presence of strong hydrogen bonding in these molecules. For both molecules, two conformers, with without H‐bond, was experimentally detected basic solvents (DMSO, acetone, pyridine) solvate complexes theoretically calculated. Specific behavior...
