Codsiga

1. Guryo badan oo ka mid ahceium carbonateIsku-dhafka dabiiciga ah wuxuu ka yimaadaa jilicsanaanta Lewis ee jilicsan ee cesium ion, taas oo ka dhigaysa mid ku milma dareerayaasha organic sida khamriga, DMF iyo ether.

2. milanka wanaagsan ee dareerayaasha organic waxay awood u siinaysaa cesium carbonate sida saldhig aan noolayn oo wax ku ool ah si ay uga qayb qaataan falcelinta kiimikaad ee ay kiciyaan reagents palladium sida falcelinta Heck, Suzuki iyo Sonogashira. Tusaale ahaan, falcelinta isku-xidhka Suzuki waxay gaari kartaa wax-soo-saarka 86% iyadoo la kaashanayo cesium carbonate, halka wax-soo-saarka fal-celinta isku midka ah ee ka-qaybgalka sodium carbonate ama triethylamine ay tahay 29% oo keliya iyo 50%. Sidoo kale, falcelinta Heck ee methacrylate iyo chlorobenzene, cesium carbonate waxay leedahay faa'iidooyin muuqda marka loo eego saldhigyada kale ee aan dabiiciga ahayn, sida potassium carbonate, sodium acetate, triethylamine, iyo potassium phosphate.

3. Cesium carbonateWaxa kale oo uu leeyahay codsi aad muhiim u ah xaqiijinta falcelinta O-alkylation ee xeryahooda phenol.

4. Tijaabooyinku waxay qiyaasaan in falcelinta phenol O-alkylation ee dareeraha aan biyaha lahayn ee ay keento cesium carbonate ay u badan tahay inay la kulmeen anions phenoloxy, markaa falcelinta alkylation waxay sidoo kale ku dhici kartaa halogens sare oo firfircoon oo u nugul falcelinta baabi'inta. .

5. Cesium carbonateWaxa kale oo uu leeyahay isticmaalka muhiimka ah ee isku-dhafka alaabta dabiiciga ah. Tusaale ahaan, isku-dhafka Lipogrammistin-A ee tallaabada muhiimka ah ee falcelinta xidhitaanka giraanta, isticmaalka cesium carbonate sida saldhig aan dabiici ahayn waxay heli kartaa alaabooyin xiran oo giraan ah oo leh waxsoosaar sare.

6. Intaa waxaa dheer, sababtoo ah milanka wanaagsan ee cesium carbonate ee dareeraha organic, waxay sidoo kale leedahay isticmaalka muhiimka ah ee falcelinta dabiiciga ah ee adag ee taageeraya. Tusaale ahaan, falcelinta saddexda qaybood ee aniline iyo halide-taageer adag ayaa lagu soo rogay jawiga carbon dioxide si ay u abuuraan xeryahooda karboxylate ama karbamate leh dhalooyin sare.

7. Shucaaca microwave-ka hoostiisa, cesium carbonate sidoo kale waxaa loo isticmaali karaa saldhig si loo xaqiijiyo falcelinta esterification ee benzoic acid iyo halogens-taageer adag.
