Intercalation/De-Intercalation Reactions of Lithium Ion at Graphite in Electrolyte Solutions Containing 3D-Transition-Metal Ions and Cyclic Ethers was written by Domi, Yasuhiro;Doi, Takayuki;Ochida, Manabu;Yamanaka, Toshiro;Abe, Takeshi;Ogumi, Zempachi. And the article was included in Journal of the Electrochemical Society in 2016.Name: 1,4,7,10-Tetraoxa-13-azacyclopentadecane This article mentions the following:

The effects of 3d-transition-metal ions in the electrolyte on the intercalation/de-intercalation reactions of Li⁺ at graphite neg.-electrodes were investigated. The edge plane of highly oriented pyrolytic graphite (HOPG) was used as a model electrode, and electrochem. properties were investigated by cyclic voltammetry and electrochem. impedance spectroscopy. A drastic decrease in redox current due to intercalation/de-intercalation reactions of Li⁺ was observed in electrolyte solutions containing Fe, Co, Ni, and Mn ions. In addition, interfacial resistance between the edge plane HOPG electrode and the electrolyte increased significantly. The effects of cyclic ethers, such as crown ether, aza crown ether, and cryptand, as electrolyte additives were applied to suppress the degradation of graphite neg.-electrodes. As a result, specific cyclic ethers greatly suppressed the degradation of edge plane HOPG neg.-electrodes in electrolyte solutions containing the above transition-metal ions. In the experiment, the researchers used many compounds, for example, 1,4,7,10-Tetraoxa-13-azacyclopentadecane (cas: 66943-05-3Name: 1,4,7,10-Tetraoxa-13-azacyclopentadecane).

1,4,7,10-Tetraoxa-13-azacyclopentadecane (cas: 66943-05-3) belongs to ethers. Ether is less polar than esters, alcohols or amines because of the oxygen atom that is unable to participate in hydrogen bonding due to the presence of bulky alkyl groups on both sides of the oxygen atom. But ether is more polar than alkenes. Ethers feature bent C闂佺偨鍎茶ぐ濠囨煃閵夛箑鐤?linkages. In dimethyl ether, the bond angle is 111闁?and C闂佺偨鍎茶ぐ?distances are 141 pm. The barrier to rotation about the C闂佺偨鍎茶ぐ?bonds is low. The bonding of oxygen in ethers, alcohols, and water is similar. In the language of valence bond theory, the hybridization at oxygen is sp3.Name: 1,4,7,10-Tetraoxa-13-azacyclopentadecane

And the article was included in Russian Journal of Organic Chemistry in 2012.Related Products of 66943-05-3 This article mentions the following:

A procedure was proposed for the synthesis of monoazacrown ethers by reaction of N-benzyldiethanolamine with oligo(ethylene glycol)-bis(p-toluene)sulfonates in a two-phase system aromatic hydrocarbon-50% aqueous alkali, followed by removal of the benzyl group by catalytic hydrogenolysis. The maximal yields of N-benzyl-aza-12-crown-4, -18-crown-6, and -21-crown-7 were achieved by adding 4-10 equiv of LiCl, BaBr₂, and CsCl, resp., to the reaction mixture, which probably indicated template effect.

Formation of organometallic species from complexes of N-phenylaza-crown ether conjugates with lead cations in CID-MS/MS conditions was written by Franski, Rafal;Ogorek, Katarzyna;Gierczyk, Blazej. And the article was included in International Journal of Mass Spectrometry in 2017.Safety of 1,4,7,10-Tetraoxa-13-azacyclopentadecane This article mentions the following:

Gas phase decomposition of the ions [M + PbNO₃]⁺ (M stands for fluoro-substituted N-nitrophenylaza-crown ether conjugate), has been studied by the electrospray ionization-collision induced dissociation-tandem mass spectrometry (ESI-CID-MS/MS). The conjugates containing hydrogen atom at ortho position to the crown moiety, form abundant fragment ions which can be assigned as complexes of deprotonated conjugates and lead cation, thus the ions [M – H + Pb]⁺ (fragment ions formed as a result of HNO₃ loss). Interaction between the nitro group (present at the second ortho position to the crown moiety) and the metal cation affects the formation of fragment ion [M – H + Pb]⁺ (but does not prevent its formation). Ions [M – H + Pb]⁺ are very rare example of the organometallic species (containing metal-carbon bond), in which metal cation is also complexed by crown ether moiety. In the experiment, the researchers used many compounds, for example, 1,4,7,10-Tetraoxa-13-azacyclopentadecane (cas: 66943-05-3Safety of 1,4,7,10-Tetraoxa-13-azacyclopentadecane).

1,4,7,10-Tetraoxa-13-azacyclopentadecane (cas: 66943-05-3) belongs to ethers. The oxygen atom in ethers are more electronegative than carbon, thus the hydrogens which are alpha to the ethers are more acidic than the simple hydrocarbons. The unique properties of ethers (i.e., that they are strongly polar, with nonbonding electron pairs but no hydroxyl group) enhance the formation and use of many reagents. For example, Grignard reagents cannot form unless an ether is present to share its lone pair of electrons with the magnesium atom. Complexation of the magnesium atom stabilizes the Grignard reagent and helps to keep it in solution.Safety of 1,4,7,10-Tetraoxa-13-azacyclopentadecane

Spin crossover in polymeric and heterometallic Fe^II species containing polytopic dipyridylamino-substituted-triazine ligands was written by Ross, Tamsyn M.;Moubaraki, Boujemaa;Batten, Stuart R.;Murray, Keith S.. And the article was included in Dalton Transactions in 2012.Formula: C10H21NO4 This article mentions the following:

The authors report the synthesis and characterization of the new polytopic ligands, ddta (N,N-di(pyridin-2-yl)-4,6-di(1,4,7,10-tetraoxa-13-azacyclopentadecan-13-yl)-1,3,5-triazin-2-amine) and tptd (N²,N²,N⁴,N⁴-tetra(pyridin-2-yl)-6-(1,4,7,10-tetraoxa-13-azacyclopentadecan-13-yl)-1,3,5-triazine-2,4-diamine). Each contains N-donor dipyridylamino binding sites as well as sep. and distinct mono-aza-15-crown-5 binding sites. The ligand ddta was used to synthesize the polymeric heterometallic spin crossover (SCO) compound trans-[Fe(II)(NCS)₂(ddta)₂Na₂](ClO₄)₂.4MeCH₂CH₂OH, (I), and tptd was used to synthesize the polymeric SCO compound trans-[Fe(II)(NCS)₂(tptd)].MeOH, (II), and the dinuclear compound cis-[(Fe(II))₂(NCS)₄(tptd)₂], (III). Magnetic susceptibility measurements show that I and a desolvated sample of III each undergo a gradual, 1-step spin transition with T₁/2 values of 閳?40 K and 閳?10 K, resp. The paucity of inter-chain intermol. interactions, as well as the flexible, covalent bridges between Fe(II) spin crossover sites, are likely to contribute to the gradual nature of the spin transition observed in each case. Variable temperature powder x-ray diffraction studies on I show the anisotropic behavior of the unit cell parameters, where c and the b-c plane are most affected by structural changes occurring as the temperature is lowered. In the experiment, the researchers used many compounds, for example, 1,4,7,10-Tetraoxa-13-azacyclopentadecane (cas: 66943-05-3Formula: C10H21NO4).

Ether is less polar than esters, alcohols or amines because of the oxygen atom that is unable to participate in hydrogen bonding due to the presence of bulky alkyl groups on both sides of the oxygen atom. But ether is more polar than alkenes. Ethers can form hydrogen bonds with other molecules (alcohols, amines, etc.) that have O閳ユ椊 or N閳ユ椊 bonds. The ability to form hydrogen bonds with other compounds makes ethers particularly good solvents for a wide variety of organic compounds and a surprisingly large number of inorganic compounds.Formula: C10H21NO4

Synthesis and photophysical properties of 2,2′-binaphthalene-based receptor bearing trimethylsilyl groups to improve the solubility was written by Kondo, Shin-ichi;Watanabe, Naoya;Takahashi, Fubuki;Takeda, Nobuhiro;Unno, Masafumi. And the article was included in Journal of Inclusion Phenomena and Macrocyclic Chemistry in 2013.Synthetic Route of C10H21NO4 This article mentions the following:

Two trimethylsilyl groups were introduced at 5- and 5′-positions of 2,2′-binaphthalene to improve the solubility of 2,2′-binaphthalene-based receptors. The x-ray crystallog. anal. revealed the twisted structure of 2 in the solid state. The solubility of 2 was moderately improved by 3.1-fold comparing with mother skeleton 1. As a practical example of 2, receptor 8 bearing two aza-15-crown-5 moieties was prepared and the selective binding of 8 with Ba²⁺ can be observed by the formation of sandwich-like complex, which shows no prevention of binding ability of the receptor by introduction of the bulky substituents.

Tautocrowns: a concept for a sensing molecule with an active side-arm was written by Antonov, Liudmil M.;Kurteva, Vanya B.;Simeonov, Svilen P.;Deneva, Vera V.;Crochet, Aurelien;Fromm, Katharina M.. And the article was included in Tetrahedron in 2010.Name: 1,4,7,10-Tetraoxa-13-azacyclopentadecane This article mentions the following:

A new sensing mol. containing aza-15-crown-5 as a receptor and 4-(phenyldiazenyl)naphthalen-1-ol as a signal converter has been synthesized. In the free ligand, the hydrogen bonding between the tautomeric OH group and the nitrogen atom from the macrocycle fully shifts the tautomeric equilibrium towards the enol form. The complexation reverses the equilibrium as a result of the strong interaction between the metal ion captured in the macrocyclic moiety and the tautomeric carbonyl group. The complex formation is accompanied by strong bathochromic (between 60 and 100 nm) and hyperchromic effects on the absorption spectra. Obviously, the tautomeric OH/C=O groups play the role of an active side-arm in the complexation, supporting it via formation of a 3D cavity and giving possibility for ejection of the guest compound under stimuli to shift the tautomeric process back. In the experiment, the researchers used many compounds, for example, 1,4,7,10-Tetraoxa-13-azacyclopentadecane (cas: 66943-05-3Name: 1,4,7,10-Tetraoxa-13-azacyclopentadecane).
