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.

Reference of 2-Methylglutaronitrile. Aromatic compounds can be divided into two categories: single heterocycles and fused heterocycles. Compound: 2-Methylglutaronitrile, is researched, Molecular C6H8N2, CAS is 4553-62-2, about Deactivation during the hydrogenation of 2-methylglutaronitrile to β-picoline. Author is Lanini, S.; Prins, R..

A strong correlation between conversion and product selectivity was found for the production of β-picoline from 2-methylglutaronitrile in a single-stage process. The conversion had to be maintained at a very high level in order to keep the intermediates concentration low, thus preventing the formation of coke precursors by condensation reactions. The intermediates concentration on the metal surface was strongly influenced by the reaction temperature and the partial pressures. Above 598 K, the selectivity for condensation products decreased sharply, but also the overall conversion decreased. This neg. effect could be compensated by an increased hydrogen partial pressure.

Two Cu(I) alkoxides, the novel compound triphenylmethoxocopper(I) and an octanuclear form of t-butoxocopper(I), were prepared from mesitylcopper(I) and the relevant alc. [Cu4(OCPh3)4]·2C6H5CH3 (1) and [Cu8(OtBu)8] (2) were characterized by crystal structure determination Compound 1 contains two crystallog. independent triphenylmethoxocopper(I) mols., each with a planar Cu4 core. The Cu4O4 unit is butterfly-shaped with the O ligands situated alternately ∼0.4 A above and below the plane through the Cu atoms, and the triphenylmethyl groups spread out over both sides of the Cu4O4 core. The Cu(I) centers are two-coordinated with distances of 1.83(1)-1.86(1) A and O-Cu-O angles of 169.4(5)°. [Cu8(OtBu)8] (2) can be described as being composed of two approx. planar Cu4O4 cores, each with the t-Bu groups bent away in the same direction from the Cu4O4 plane. These units are related to one another by a center of symmetry and with weak Cu-O interactions of 2.493(5) and 2.536(5) A, involving four of the eight coppers, thus yielding an octanuclear Cu8O8 core. These four Cu(I) centers thus attain T-shaped three-coordination by O, whereas the remaining four are approx. linearly coordinated. The short Cu-O bond lengths in 2 range from 1.844(5) to 1.888(5) A.

Compound: 2-Methylglutaronitrile, is researched, Molecular C6H8N2, CAS is 4553-62-2, about Inhalation toxicity of methylglutaronitrile in rats.

Methylglutaronitrile (MGN) is a high-boiling (263°) solvent/intermediate used in the fiber industry. Twenty male rats per group were exposed nose-only to condensation aerosol/vapor concentrations of approx. either 5, 25, or 200 mg/m3 MGN for 6 h/day, 5 days/wk over a 4-wk period. Ten rats/group were sacrificed 1 day after the final exposure and the remaining rats after a 4-wk recovery period. No effects were observed in clin. observations during the exposure period, but body-weight depression was observed in the 200-mg/m3 group. The 200-mg/m3 group showed minimal decreases in red blood cell count, Hb, and hematocrit values accompanied by increases in reticulocytes. There were no other effects observed in clin. or pathol. evaluations in the study. A neurobehavioral battery of tests (including grip strength, functional observational battery, and motor activity tests) given at the end of the exposure and recovery periods showed no MGN effects. During the 4-wk recovery, body weights in the 200-mg/m3 group returned to normal and the hematol. findings in all the groups were normal. Based on the above findings of body weight depression at 200 mg/m3, the no-observed-adverse-effect level (NOAEL) for this study was considered to be 25 mg/m3.

The three-dimensional configuration of the ester heterocycle is basically the same as that of the carbocycle. Compound: (2S)-(+)-3-Chloropropane-1,2-diol(SMILESS: OC[C@H](O)CCl,cas:60827-45-4) is researched.HPLC of Formula: 111-18-2. The article 《Study on acute toxicity of R,S and (R,S)-3-chloro-1,2-propanediol》 in relation to this compound, is published in Weisheng Yanjiu. Let’s take a look at the latest research on this compound (cas:60827-45-4).

The aim of the paper was to investigate the acute toxicity of R,S and (R,S)-3-chloro-1,2-propanediol (3-MCPD). Ten, seven and seven groups of sexually mature ICR mice were employed for testing the acute toxicity of R, S and (R,S)-3-MCPD, at the doses of 176.78 mg/kg, 198.43 mg/kg, 222.73 mg/kg, 250 mg/kg, 280.61 mg/kg, 314.98 mg/kg, 353.55 mg/kg, 396.84 mg/kg, 445.44 mg/kg, and 499.99 mg/kg for R-3-MCPD, 89.09 mg/kg, 100 mg/kg, 112.25 mg/kg, 125.99 mg/kg, 141.42 mg/kg, 158.74 mg/kg and 178.18 mg/kg for S-3-MCPD, and 130.25 mg/kg, 150 mg/kg, 172.75 mg/kg, 198.95 mg/kg, 229.13 mg/kg, 263.88 mg/kg and 303.91 mg/kg for (R,S)-3-MCPD, resp. The mice were given three forms of 3-MCPD once by gavage and observed for 14 days, the LD50 was calculated by the modified Karber’s method, and organ/body weight ratios were measured and morphol. changes of liver and kidney were examined Results showed that the LD50 (95% CI) of R, S and (R,S)-3-MCPD was 290.54 mg/kg (280.74-300.68), 117.57 mg/kg (113.82-121.45) and 190.73 mg/kg (177.76-204.59), resp. The kidney/weight ratios in R-3-MCPD treated groups were higher than controls at the doses of 250-353.55 mg/kg (P < 0.05), and the brain weight ratios also had an significant increase in the 353.55 mg/kg, 445.44 mg/kg and above doses (P < 0.05). However, no significant changes on organ/body weight ratio of any organs in S-3-MCPD treated groups were observed The kidney/body weight ratio in (R,S)-3-MCPD treated groups increased significantly at the doses of 198.95-303.91 mg/kg (P < 0.05), and the brain weight ratios also had a significant increase at the doses of 229.13-303.91 mg/kg. At the doses of 353.55-499.99mg/kg, R-3-MCPD caused obvious swell of liver cells and the swell and congestion of the liver sinus. At the dose 229.13 mg/kg and above, (R,S)-3-MCPD also induced the swell of liver cells and congestion of the liver sinus. No obvious morphol. change of kidney after administration of R, S and (R,S)-3-MCPD was observed In conclusion, the acute toxicity of S-3-MCPD might be much higher than those of (R,S)-3-MCPD and R-3-MCPD, and both R-3-MCPD and S-3-MCPD seemed to possess neurotoxicity.
