Cesium carbonate 534-17-8 mtengo wopanga

Pali katundu wokwanira, wapamwamba kwambiri komanso kutumiza mwachangu. Kuchuluka kochulukira ndi kuchotsera.
Zofunikira zilizonse, talandiridwa kuti mutilankhule nthawi iliyonse.

Kugwiritsa ntchito

1. Zambiri zacesium carbonatemu organic synthesis amachokera ku Lewis acidity yofewa ya cesium ion, yomwe imapangitsa kuti isungunuke muzosungunulira organic monga mowa, DMF ndi ether.

2. The solubility wabwino mu zosungunulira organic chimathandiza cesium carbonate monga ogwira inorganic m'munsi kutenga nawo mbali mu zimachitikira mankhwala catalyzed ndi palladium reagents monga Heck, Suzuki ndi Sonogashira zimachitikira. Mwachitsanzo, Suzuki mtanda lumikiza anachita akhoza kukwaniritsa zokolola za 86% ndi thandizo la cesium carbonate, pamene zokolola za anachita chimodzimodzi ndi nawo sodium carbonate kapena triethylamine yekha 29% ndi 50%. Mofananamo, mu Heck reaction ya methacrylate ndi chlorobenzene, cesium carbonate ili ndi ubwino wodziwikiratu kuposa maziko ena achilengedwe, monga potassium carbonate, sodium acetate, triethylamine, ndi potassium phosphate.

3. Cesium carbonateilinso ndi ntchito yofunika kwambiri pakuzindikira O-alkylation reaction ya phenol compounds.

4. Mayesero amalingalira kuti phenol O-alkylation reaction mu zosungunulira zopanda madzi zomwe zimayambitsidwa ndi cesium carbonate zikhoza kukhala ndi ma anions a phenoloxy, kotero kuti alkylation reaction ingathenso kuchitika kwa ma halogens apamwamba kwambiri omwe amatha kuchotsedwa. .

5. Cesium carbonateilinso ndi ntchito zofunika popanga zinthu zachilengedwe. Mwachitsanzo, mu kaphatikizidwe ka Lipogrammistin-A pawiri mu gawo lofunikira la kutseka kwa mphete, kugwiritsa ntchito cesium carbonate ngati maziko achilengedwe kumatha kupeza zinthu zotsekedwa zokhala ndi zokolola zambiri.

6. Kuonjezera apo, chifukwa cha kusungunuka kwabwino kwa cesium carbonate mu zosungunulira za organic, imakhalanso ndi ntchito zofunika pazochitika zolimba zothandizidwa ndi organic. Mwachitsanzo, mawonekedwe a zigawo zitatu za halide ya aniline ndi yolimba-mothandizidwa ndi mpweya wa carbon dioxide kuti apange mankhwala a carboxylate kapena carbamate ndi zokolola zambiri.

7. Pansi pa cheza cha mayikirowevu, cesium carbonate angagwiritsidwenso ntchito ngati maziko kuzindikira esterification anachita wa asidi benzoic ndi olimba-anathandiza halojeni.
