Kub Muag thiab Zoo Zoo Cesium Carbonate CAS 534-17-8 nrog Tus Nqi Zoo

PrM ntau yam khoom ntawm cesium carbonate nyob rau hauv cov organic synthesis yog muab los ntawm mos Lewis acidity ntawm cesium ion, uas ua rau nws soluble nyob rau hauv organic solvents xws li cawv, DMF thiab ether.Qhov zoo dua solubility nyob rau hauv cov kuab tshuaj organic enables cesium carbonate koom nyob rau hauv cov tshuaj tiv thaiv catalyzed los ntawm palladium reagents raws li ib tug zoo inorganic puag, xws li Heck, Suzuki thiab Sonogashira cov tshuaj tiv thaiv.Piv txwv li, Suzuki cross coupling cov tshuaj tiv thaiv nrog cesium carbonate tau txais 86% tawm los, thaum tib cov tshuaj tiv thaiv nrog sodium carbonate lossis triethylamine tsuas yog 29% thiab 50%.Ib yam li ntawd, hauv Heck cov tshuaj tiv thaiv ntawm methacrylate thiab chlorobenzene, cesium carbonate piv nrog rau lwm cov hauv paus inorganic, xws li potassium carbonate, sodium acetate, triethylamine, potassium phosphate, pom tau tias muaj txiaj ntsig zoo heev.Cesium carbonate kuj muaj cov ntawv thov tseem ceeb hauv o-alkylation ntawm phenol tebchaw.Nws yog speculated tias phenol O-alkylation cov tshuaj tiv thaiv nyob rau hauv cesium carbonate uas tsis yog-aqueous hnyav yuav muaj kev paub txog phenoxyethylene anion, yog li cov tshuaj tiv thaiv alkylation kuj tuaj yeem tshwm sim rau theem nrab halogenates nrog kev ua haujlwm siab thiab tshem tawm cov tshuaj tiv thaiv yooj yim.Cesium carbonate kuj muaj cov ntawv thov tseem ceeb hauv kev sib txuas ntawm cov khoom ntuj.Piv txwv li, nyob rau hauv cov synthesis ntawm Lipogrammisin-ib compound nyob rau hauv Ib kauj ruam tseem ceeb kaw-voj cov tshuaj tiv thaiv, cesium carbonate raws li ib tug inorganic puag yuav siv tau kom tau kaw-voj khoom nrog high yield.Tsis tas li ntawd, cesium carbonate muaj cov ntawv thov tseem ceeb hauv cov khoom txhawb nqa cov tshuaj tiv thaiv kab mob vim nws cov solubility zoo hauv cov kuab tshuaj organic.Carboxylate los yog carbamate tebchaw tuaj yeem raug tsim los ntawm cov txiaj ntsig siab los ntawm kev ua rau peb cov tshuaj tiv thaiv ntawm aniline nrog cov khoom txhawb nqa halogen hauv cov pa roj carbon dioxide.Nyob rau hauv microwave irradiation, cesium carbonate kuj tseem siv tau los ua lub hauv paus kom paub txog cov tshuaj tiv thaiv esterification ntawm benzoic acid thiab cov khoom txhawb nqa halogenates.
