| siv |
15-crown-5 kuj tau siv los cais cov ntsev ntawm oxonium ions. Piv txwv li, los ntawm kev daws ntawm tetrachloroauric acid, oxonium ion [H7O3]+ tau raug cais raws li ntsev [(H7O3)(15-crown-5)2][AuCl4]. |
| Taw qhia |
Ib qho nitrogen-muaj derivative ntawm 15-crown-5 hu ua aza-15-crown-5; lub prefix "mono" yog tsis tsim nyog. Thaum muaj ob los yog ntau tshaj nitrogen atoms, tus qauv prefixes di-, tri-, thiab lwm yam. Lo lus "monoazacrowns" yog siv rau ntawm no los xaiv cov chav kawm ntawm macrocycles uas muaj ib qho nitrogen hauv kev sib xyaw nrog oxygen atoms raws li macrocyclic pub array. |

| Siv | 15-Crown-5 yog siv los ua cov txheej txheem hloov pauv hloov pauv tau zoo thiab ua tus neeg sawv cev nyuaj. Nws yog siv los cais oxonium ion (H7O3) + ntsev tshwj xeeb tshaj yog los ntawm kev daws ntawm tetrchloroauric acid. Nws catalyzes O-alkylation ntawm sodium ntsev ntawm carboxylic acids nyob rau hauv penicillin thiab cephalosporin series, yog li yooj yim esterification cov tshuaj tiv thaiv yam tsis tau siv cov kua qaub. Nws kuj yog siv los pab txhawb Williamson synthesis ntawm ethers nrog hindered alcohols thiab sodium hydride. Nws yog siv nrog lithium aluminium hydride, rau kev ua haujlwm txo qis hauv cov kuab tshuaj hydrocarbon. Tsis tas li ntawd, nws tau koom nrog hauv Horner-Wadsworth-Emmons cov tshuaj tiv thaiv los npaj stilbenes los ntawm aldehydes. |
| Txhais | ChEBI: Ib tug saturated organic heteromonocyclic niam txiv uas yog cyclopentadecane nyob rau hauv uas cov pa roj carbon atoms ntawm txoj hauj lwm 1, 4, 7, 10 thiab 13 tau hloov los ntawm oxygen atoms muab ib tug crown ether. |
| Kev piav qhia dav dav | 15-Crown-5 yog ib qho yas ether feem ntau siv los ua ligand hauv kev sib koom tes chemistry vim nws cov khoom muaj zog chelating nrog qee cov alkali cations los tsim cov complexes. Qee qhov derivatives ntawm 15-crown-5 yog siv los ua sensors thiab sojntsuam hauv cov txheej txheem sib txawv ntawm lub cev-tshuaj lom neeg, theem-hloov cov tshuaj tiv thaiv, thiab xaiv ntes ions rau kev sib cais thiab thauj. |
| Kev ruaj ntseg Profile | Muaj tshuaj lom los ntawm kev noj, kev sib cuag ntawm daim tawv nqaij, thiab txoj hauv kev intraperitoneal. Ib daim tawv nqaij thiab qhov muag. Thaum rhuab mus rau decomposition nws emissions pa luam yeeb thiab irritating fumes |
| Txoj Kev Purification | Qhuav nws tshaj 3A molecular sieves thiab distil nws nyob rau hauv lub siab nqus tsev vacuum. [Beilstein 19/12 V 252.] |
