I-Cesium carbonate 534-17-8 intengo yokukhiqiza

Kukhona isitoko esanele, ikhwalithi ephezulu kanye nokulethwa okusheshayo. Inani elengeziwe elinesaphulelo esengeziwe.
Noma yiziphi izidingo, wamukelekile ukuxhumana nathi nganoma yisiphi isikhathi.

Isicelo

1. Izakhiwo eziningi zei-cesium carbonateku-organic synthesis ivela ku-Lewis acidity ethambile ye-cesium ion, eyenza inyibilikiseke kuzincibilikisi zemvelo ezifana notshwala, i-DMF ne-ether.

2. Ukuncibilika okuhle kuzincibilikisi zemvelo kwenza i-cesium carbonate njengesisekelo sezinto ezingaphili ezisebenzayo ukuthi ibambe iqhaza ekuphenduleni kwamakhemikhali okubangelwa ama-reagents e-palladium afana nokusabela kwe-Heck, i-Suzuki ne-Sonogashira. Isibonelo, ukusabela kwe-Suzuki cross-coupling kungazuza isivuno esingu-86% ngokusekelwa kwe-cesium carbonate, kuyilapho isivuno sokusabela okufanayo ngokubamba iqhaza kwe-sodium carbonate noma i-triethylamine kuphela ku-29% no-50%. Ngokufanayo, ekuphenduleni kukaHeck kwe-methacrylate ne-chlorobenzene, i-cesium carbonate inezinzuzo ezisobala ngaphezu kwezinye izisekelo ze-inorganic, njenge-potassium carbonate, i-sodium acetate, i-triethylamine, ne-potassium phosphate.

3. I-Cesium carbonatefuthi inesicelo esibaluleke kakhulu ekuboneni ukusabela kwe-O-alkylation kwama-phenol compounds.

4. Ukuhlola kucatshangelwa ukuthi ukusabela kwe-phenol O-alkylation kuzincibilikisi ezingenawo amanzi ezibangelwa i-cesium carbonate kungenzeka kube ne-phenoloxy anions, ngakho-ke ukusabela kwe-alkylation kungase kwenzeke kuma-halogens yesibili asebenza kakhulu ajwayele ukusabela ekuqedeni. .

5. I-Cesium carbonatefuthi inokusetshenziswa okubalulekile ekuhlanganiseni kwemikhiqizo yemvelo. Isibonelo, ekuhlanganisweni kwenhlanganisela ye-Lipogrammistin-A esinyathelweni esiyinhloko sokusabela kokuvala indandatho, ukusetshenziswa kwe-cesium carbonate njengesisekelo se-inorganic kungathola imikhiqizo evaliwe enezivuno eziphezulu.

6. Ukwengeza, ngenxa yokuncibilika okuhle kwe-cesium carbonate kuzincibilikisi zemvelo, iphinde ibe nokusetshenziswa okubalulekile ekuphenduleni okuqinile okusekelwa kwe-organic. Isibonelo, ukusabela kwezingxenye ezintathu ze-aniline kanye ne-halide esekelwe ngokuqinile iyengelwa emkhathini we-carbon dioxide ukuze kuhlanganiswe i-carboxylate noma izinhlanganisela ze-carbamate ezinesivuno esikhulu.

7. Ngaphansi kwemisebe ye-microwave, i-cesium carbonate ingasetshenziswa futhi njengesisekelo sokubona ukusabela kwe-esterification ye-benzoic acid nama-halogen asekelwe ngokuqinile.
