Epoxy compounds usually have stronger nucleophilic ability, because the alkyl group on the oxygen atom makes the bond angle smaller, which makes the lone pair of electrons react more dissimilarly with the electron-deficient system. Compound: 5,10,15,20-Tetrakis (4-methoxyphenyl)-21H,23H-porphine cobalt (II), is researched, Molecular C48H38CoN4O4, CAS is 28903-71-1, about Effect of N,N,N’-trimethylpiperazinium (TMP+) cations on magnetic properties and dimerization of fullerenes in the (TMP+)(CoIIporphyrin)(C-60) salts.Name: 5,10,15,20-Tetrakis (4-methoxyphenyl)-21H,23H-porphine cobalt (II).
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. When you point to this article, it is believed that you are also very interested in this compound(28903-71-1)Name: 5,10,15,20-Tetrakis (4-methoxyphenyl)-21H,23H-porphine cobalt (II) and due to space limitations, I can only present the most important information.
