1,4,7,10-Tetraoxa-13-azacyclopentadecane (cas: 66943-05-3) belongs to ethers. Ethers are good solvents partly because they are not very reactive. Most ethers can be cleaved, however, by hydrobromic acid (HBr) to give alkyl bromides or by hydroiodic acid (HI) to give alkyl iodides. Autoxidation is the spontaneous oxidation of a compound in air. In the presence of oxygen, ethers slowly autoxidize to form hydroperoxides and dialkyl peroxides. If concentrated or heated, these peroxides may explode. To prevent such explosions, ethers should be obtained in small quantities, kept in tightly sealed containers, and used promptly.Application of 66943-05-3

Phosphorus-nitrogen compounds: Part 61. The novel sodium complexes of monoferrocenylspirocyclotriphosphaza-crown ethers was written by Uzunalioglu, Nese;Asmafiliz, Nuran;Kilic, Zeynel;Hokelek, Tuncer. And the article was included in Inorganica Chimica Acta in 2022.Application of 66943-05-3 This article mentions the following:

Condensation reactions of hexachlorocyclotriphosphazene, N3P3Cl6 (HCCP, trimer) and four different diamines (1–4) yielded tetrachloromono (5, 7 and 8) and bisferrocenyl (6) spirocyclotriphosphazenes. Reactions of 5, 7 and 8 with two equimolar amounts of 1-aza-15-crown-5 ether (L) produced new monoferrocenylspirocyclotriphosphazabis(crown ethers) (9, 10 and 12) in THF, resp. The only monoferrocenylspirocyclotriphosphazatris(crown ether) (13) was obtained from the reaction of 8 with three equimolar amounts of L. However, reactions of 7 and 8 with four equimolar amounts of L gave monoferrocenylspirocyclotriphosphaza-tetrakis(crown ethers) 11 and 14. In addition, the complexation reactions of ditopic phosphaza-crown ethers (9, 10 and 11) with NaClO4 yielded novel mononuclear sandwich-type sodium complexes (9a, 10a and 11a). Tri- and tetranuclear complexes (13a and 14a) were obtained as a result of the complexation reactions of tri- and tetratopic phosphaza-crown ethers (13 and 14) with NaClO4. Characterizations of phosphaza-crown ethers and complexes were performed using elemental anal., mass spectrometry, FTIR, and 1H, 13C and 31P NMR techniques. Ditopic phosphazenes (9, 10 and 12) and complexes (9a, 10a and 11a) have a stereogenic P center. While the tritopic ligand (13) and complex (13a) have two stereogenic P centers. They are expected to be in racemic mixtures In addition, crystal structures of phosphazenes 6 and 9 were elucidated using x-ray crystallog. The absolute configurations of the enantiomers of 9 were determined as R and S. Furthermore, intermol. interactions in crystal structures of 6 and 9 were determined by Hirshfeld surface (HS) anal. In the experiment, the researchers used many compounds, for example, 1,4,7,10-Tetraoxa-13-azacyclopentadecane (cas: 66943-05-3Application of 66943-05-3).
