Most of the natural products isolated at present are heterocyclic compounds, so heterocyclic compounds occupy an important position in the research of organic chemistry. A compound: 28903-71-1, is researched, SMILESS is COC1=CC=C(C=C1)C(C2=[N]3[Co+2]4([N-]56)[N-]7C(C(C8=CC=C(C=C8)OC)=C3C=C2)=CC=C7C(C9=CC=C(C=C9)OC)=C%10C=CC%11=[N]4%10)=C5C=CC6=C%11C%12=CC=C(C=C%12)OC, Molecular C48H38CoN4O4Journal, Inorganica Chimica Acta called Effect of N,N,N’-trimethylpiperazinium (TMP+) cations on magnetic properties and dimerization of fullerenes in the (TMP+)(CoIIporphyrin)(C-60) salts, Author is Konarev, Dmitri V.; Khasanov, Salavat S.; Lyubovskaya, Rimma N., the main research direction is trimethylpiperazinium cobalt porphyrinato complex fullerene anion preparation crystal structure; magnetism trimethylpiperazinium cobalt porphyrinato complex fullerene anion.Formula: C48H38CoN4O4.

New salts of fullerene C•-60 radical anions with N,N,N’-trimethylpiperazinium cations (TMP+) containing neutral cobalt(II) porphyrin mols.: {(TMP+)·CoIIOEP}·(C•-60)·2C6H4Cl2·C6H5CN (1) and (TMP+)3{CoIITMPP·(C-60)}2(C•-60) ·C6H4Cl2·C6H5CN (2) were obtained (OEP and TMPP are octaethyl- or tetrakis(4-methoxyphenyl)porphyrins, resp.). In these salts the C•-60 radical anions or the TMP+ cations with free nitrogen atom can coordinate to cobalt(II) porphyrins and form Co-C(C-60) or Co-N(TMP+) bonds. The properties of these salts and the possibility of fullerene dimerization depend on type of bonds formed. For example, TMP+ cations in 1 form coordination (TMP+)·CoIIOEP assemblies preserving free nonbonded C•-60 radical anions. They are effectively coupled with S = 1/2 spins localized on CoIIOEP (Weiss temperature is -27 K and decrease of magnetic moment of 1 is observed <150 K). Previously the {(MDABCO+)·CoIITMPP}2·(C-60)2·(C6H4Cl2)2.5·(C6H5CN)1.5 salt was obtained in which doubly-bonded (C-60)2 dimers were found. In contrast to this salt, TMP+ cations in 2 preserved uncoordinated allowing the formation of the Co-C(C-60) bond of 2.273(3) Å length in the diamagnetic σ-bonded CoIITMPP·(C-60) anions. In coordinated state, fullerene anions cannot dimerize in 2 in spite of that their mutual arrangement and short interfullerene distances are favorable for such dimerization. Thus, variation of cations in the (Cation+)(CoIIporphytin)(C-60) salts drastically affects their properties and allows one to control dimerization of fullerene anions.

Glazkova, M. E.; Ageeva, T. A.; Rodina, Yu. S.; Koifman, O. I. published an article about the compound: 5,10,15,20-Tetrakis (4-methoxyphenyl)-21H,23H-porphine cobalt (II)( cas:28903-71-1,SMILESS:COC1=CC=C(C=C1)C(C2=[N]3[Co+2]4([N-]56)[N-]7C(C(C8=CC=C(C=C8)OC)=C3C=C2)=CC=C7C(C9=CC=C(C=C9)OC)=C%10C=CC%11=[N]4%10)=C5C=CC6=C%11C%12=CC=C(C=C%12)OC ).Recommanded Product: 5,10,15,20-Tetrakis (4-methoxyphenyl)-21H,23H-porphine cobalt (II). Aromatic heterocyclic compounds can be classified according to the number of heteroatoms or the size of the ring. The authors also want to convey more information about this compound (cas:28903-71-1) through the article.

The article presents the results of the kinetics study of the cobalt porphyrins interaction with radical polymerization initiators – benzoyl peroxide and lauryl peroxide in solution by the spectrophotometric method. From disparate literature data, it is known that some metalloporphyrins can interact with benzoyl peroxide to form the tautomers of porphyrins – isoporphyrins. These compounds have a number of specific properties, for example, it can be catalysts of various processes. Perhaps the isoporphyrins formation is the reason for high activity of the initiating systems “”cobalt porphyrin – benzoyl peroxide”” in the polymerization of vinyl monomers. Cobalt(II)complexes of tetraphenylporphyrin, tetra-p-methoxyphenylporphyrin, 5,15-bis(4′-tert-butylphenyl)-3,7,13,17-tetramethyl-2,8,12,18-tetra-p-butylporphyrin were selected as the objects of this study. The influence of the porphyrin ligand structure on the formation of cobalt isoporphyrins was estimated The interaction of cobalt (II) tetraphenylporphyrin and cobalt (II) tetra-para-methoxyphenylporphyrin with peroxides showed changes in the electronic absorption spectra of metalloporphyrins: deformation of the Soret band, reduction of the absorption band in the visible region, and the appearance of absorption bands in the near IR region. These changes are characteristic for metalloisoporphyrins. Data on the interaction of cobalt porphyrins with lauryl peroxide were obtained for the first time. The formation of isoporphyrins is possible with the different ratio of concentrations of reagents: with a lack of peroxide, with equimolar ratio, and also with a significant (100-fold) excess of peroxide. When 5,15-bis(4′-tert-butylphenyl)-3,7,13,17-tetramethyl-2,8,12,18-tetra-p-butylporphyrinate cobalt (II) reacted with peroxides, no isoporphyrinates were observed The article presents the effective reaction rate constants of the cobalt isoporphyrinates formation at 25°C.It is shown that the structure of both cobalt porphyrinates and organic peroxides affects the possibility and rate of isoporphyrins formation.

Recommanded Product: 5,10,15,20-Tetrakis (4-methoxyphenyl)-21H,23H-porphine cobalt (II). The protonation of heteroatoms in aromatic heterocycles can be divided into two categories: lone pairs of electrons are in the aromatic ring conjugated system; and lone pairs of electrons do not participate. Compound: 5,10,15,20-Tetrakis (4-methoxyphenyl)-21H,23H-porphine cobalt (II), is researched, Molecular C48H38CoN4O4, CAS is 28903-71-1, about Pyrolyzed Co-Nx/C electrocatalysts supported on different carbon materials for oxygen reduction reaction in neutral solution. Author is Zhang, Lei; Ye, Daixin; Huang, Qiu-An; Zhao, Hongbin; Shao, Qinsi; Zhang, Jiujun.

In this work, a non-noble metal material, i.e., 5, 10, 15, 20-Tetrakis(4-methoxyphenyl)-21H, 23H-porphine cobalt(II) (CoTMPP), is chosen as the metal complex which adsorbs on three different carbon support materials, namely, black pearls 2000 (BP), ordered mesoporous carbon (MPC) and single layer graphene oxide (GO), to form CoTMPP/BP, CoTMPP/MPC, and CoTMPP/GO catalyst precursors, resp. These precursors are heat-treated at high temperatures to form Co-Nx/BP, Co-Nx/MPC, and Co-Nx/GO catalysts for ORR in neutral electrolyte solution, resp. Several characterization methods including XRD, SEM/TEM and XPS are employed. Electrochem. methods such as cyclic voltammetry (CV), rotating disk electrode (RDE) and rotating ring-disk electrode (RRDE) techniques are used to quant. measure the catalyzed ORR kinetic parameters. Effects of both carbon supports and heat-treatment temperature on the catalyst phys. properties and catalytic ORR activities were also studied. Regarding the catalytic ORR activity, the activity order was measured as: Co-Nx/BP > Co-Nx/MPC > Co-Nx/GO. The overall electron transfer number catalyzed by Co-Nx/BP is measured to be 4, while those by Co-Nx/MPC and Co-Nx/GO catalysts are 2-electron transfer pathways. Based on these measurements and our anal., an ORR mechanism is also proposed for facilitating further investigation and understanding.
