The direct electro-reduction of CO2 to functional molecules like ethene is a highly desirable variant of CO2 utilization. The formation of, for example, ethene from CO2 is a multistep electrochemical process going through various intermediates. As these i... see more

Carbene variations of a series of fundamental reactions, the features of their course in comparison with classical analogues have been first summarized and analyzed in the review. A number of carbene transformations described in the literature relates to ... see more

For carbenes as ambiphilic compounds there is no single scale for estimating their electron properties.Aim. To consider the known methods of estimating the electron-donating and electron-withdrawing properties of carbenes, first of all, created by the aut... see more

Carbenes are known to be highly reactive compounds, which can, in turn, spontaneously transform to dimers and products of rearrangements. Therefore, the question about the estimation of stability of carbenes is fundamental in the design of compounds for t... see more

The present article describes the synthesis of new 4,4-spiroalkenic 1,2-diarylpyrazolidine-3,5-diones by ring-closing metathesis reactions (RCM). They may be potential biological active compounds since a great quantity of 1,2-diazoles show a wide spectrum... see more

A new N, N'-imidazolium salt 1-(2,6-diisopropylphenyl)-3- (4,6-dimorpholino -1,3,5-traizine-2-yl)-1H-imidazol-3-ium chloride) as a precursor of N - heterocyclic carbene ligand was prepared via the reaction of 1 - (2, 6 - diisopropyl phenyl - 1H - imidazol... see more

Novel Group VI transition metal Fischer carbene complexes containing three different transition metal substituents, all in electronic contact with the carbene carbon atom, were synthesised.

A new N, N'-imidazolium salt 1-(2,6-diisopropylphenyl)-3- (4,6-dimorpholino -1,3,5-traizine-2-yl)-1H-imidazol-3-ium chloride) as a precursor of N - heterocyclic carbene ligand was prepared via the reaction of 1 - (2, 6 - diisopropyl phenyl - 1H - imidazol... see more

The effect of singlet–triplet splitting in C2–carbenes on the intermolecular proton rearrangement with minimum activation energies was stated by quantum chemical calculations. It is shown that energy barriers of the proton rearrangement by 1?2 shift mecha... see more
