    Synthesis and properties of azines functionalized graphene with extremely high adsorptive ability to Eu3+ ions / O. N. Chupakhin, A. A Musikhina, I. A. Utepova [et al.] // Flatchem. - 2022. - Vol. 33. - P100348
Рубрики: ХИМИЧЕСКИЕ НАУКИ
Аннотация: In this work, a versatile synthetic protocol for obtaining of new promising carbon materials based on the C–C coupling of graphenide lithium species with azaaromatic compounds (1,10-phenanthroline, phenyl-1,2,5-oxadiazolo[3,4-b]pyrazine) has been suggested. It was shown that more electrophilic oxadiazolopyrazine gave the product with high degree of graphene functionalization and demonstrated non-isomorphic properties. At the same time, phenanthrolinyl graphene has less functionalization degree due to a lower electrophilicity of azine. However, the large size of pores between organic residues in phenanthrolinyl graphene allows adsorbing almost 10% of Eu3+. The mesurment of adsorption isotherm showed an extremely high affinity of phenanthrolinylgraphene to Eu (III) ions in netural or alkaline conditions, and the obtained hybrid material could work at least 5 sorption/desorption cycles. The structures of azine-graphene dyads were verified by complex of modern physicochemical analyses methods (the Raman spectroscopy, FTIR, XPS, SEM, EDS and TGA analyses).

Аннотация: The SN H methodology has successfully been applied for the direct C(sp2)-H functionalization of azaaromatics through the C-Li/C-H coupling of pentafluorophenyl lithium with azines and their N-oxides. As a result, a number of novel fluorinated biheterocyclic ensembles, that are of interest in the design of bioactive molecules and advanced materials, have been prepared in good to excellent yields under rather mild condition.

HYDRIDE TRANSFER-REACTIONS -- AROMATIC-SUBSTITUTION -- NUCLEOPHILIC-SUBSTITUTION
Аннотация: Data on anodic dehydroaromatization of 9,10-dihydroacridines, bearing aryl and heteroaryl fragments, are presented. Effects of both electron-donating and electron-withdrawing substituents on the current-voltage characteristics of these compounds have been established. The experimental data proved to be in a good agreement with quantum chemical calculations. A simple and convenient method for the electrochemical conversion of dihydroacridines into the corresponding 9-(hetero)aryl-N-methylacridinium salts has been advanced

NUCLEOPHILIC SUBSTITUTION -- HYDROGEN -- ARENES AND HETARENES
Аннотация: The review considers the most typical examples of the direct non-activated non-catalytic C–C bond formation in arenes and their metal complexes activated by electron-withdrawing substituents in the aromatic nucleus and in hetarenes (azines and their N-oxides, porphyrins, etc.) upon the reactions with aliphatic and (hetero)aromatic (hetero)organolithium nucleophiles. Particular attention is given to the direct introduction of nitroxide radicals and (hetero)organic moieties into mono-, di- and triazines and their N-oxides. The influence of the structures of the (hetero)aromatic substrate and the (hetero)organolithium nucleophile on the reaction pathway and rate and on the structure of the reaction product is analyzed.

Аннотация: In this paper we wish to report a highly selective and benign method for the double C-H/C-H coupling of azaaromatics with indoles or pyrrole in the presence of air oxygen/TiO2, as an effective photocatalytic oxidative system. It has been shown that this versatile approach can be applied for direct C-H functionalisation of a variety of azaaromatic systems, such as mono-, di- and triazines, substituted and unsubstituted azines and their benzo-annelated analogues.

CHIRAL AZINYLFERROCENES -- CROSS-COUPLING REACTION -- HALOGENATED AZINES
Аннотация: Two synthetic routes to the chiral azinylferrocenes (CAFs) 5 and 15, key intermediates for the synthesis of new enantiomerically enriched P,N-ligands, have been compared. The first approach is based on the palladium-catalyzed cross-coupling reaction of halogenated azines with organozinc derivatives of ferrocenes (the Negishi reaction). The second approach exploits a new synthetic methodology, which provides a shorter pathway, through the direct C–H functionalization of aromatics by the C–C coupling of halogen-free (hetero)arenes with lithium ferrocenes bearing stereogenic C and S atoms. The palladium complexes of P,N-ligands have been used as catalysts for the Tsuji–Trost reaction, which proceeds with high enantioselectivity to give allylic substitution products in good yields.
