1. Lintho tse ngata tsacesium carbonateka har'a organic synthesis e tsoa ho Lewis acidity e bonolo ea cesium ion, e etsang hore e qhibilihe ka har'a metsoako ea lintho tse phelang tse kang joala, DMF le ether.

2. The hantle solubility ka solvents manyolo nolofalletsa cesium carbonate e le e atlehang inorganic botlaaseng ho nka karolo karabelong ea lik'hemik'hale catalyzed ke palladium reagents tse kang Heck, Suzuki le Sonogashira reactions. Ka mohlala, karabelo ea Suzuki cross-coupling e ka finyella lihlahisoa tsa 86% ka tšehetso ea cesium carbonate, ha lihlahisoa tsa karabelo e tšoanang le ho kenya letsoho ha sodium carbonate kapa triethylamine ke 29% feela le 50%. Ka mokhoa o ts'oanang, ts'ebetsong ea Heck ea methacrylate le chlorobenzene, cesium carbonate e na le melemo e totobetseng ho feta metheo e meng e sa tloaelehang, e kang potassium carbonate, sodium acetate, triethylamine, le phosphate potassium.

3. Cesium carbonatee boetse e na le ts'ebeliso ea bohlokoa haholo ho elelloa karabelo ea O-alkylation ea metsoako ea phenol.

4. Liteko li hakanya hore phenol O-alkylation reaction ka li-solvents tse se nang metsi tse bakoang ke cesium carbonate e ka 'na ea e-ba le phihlelo ea phenoloxy anions, kahoo alkylation reaction e ka boela ea etsahala bakeng sa li-halogen tsa bobeli tse nang le ts'ebetso e phahameng tse atisang ho fetoha. .

5. Cesium carbonatee boetse e na le ts'ebeliso ea bohlokoa ha ho etsoa lihlahisoa tsa tlhaho. Ka mohlala, ha ho etsoa motsoako oa Lipogrammistin-A mohato o ka sehloohong oa karabelo ea ho koala lesale, tšebeliso ea cesium carbonate e le setsi sa inorganic e ka fumana lihlahisoa tse koetsoeng tse nang le lihlahisoa tse ngata.

6. Ho phaella moo, ka lebaka la ho qhibiliha ha cesium carbonate ka har'a li-solvents tsa organic, e boetse e na le litšebeliso tsa bohlokoa litabeng tsa tlhaho tse tšehetsoeng ka thata. Ka mohlala, karabelo ea likarolo tse tharo tsa aniline le halide e tšehelitsoeng ka thata e susumetsoa moeeng oa carbon dioxide ho kopanya metsoako ea carboxylate kapa carbamate e nang le chai e ngata.

7. Tlas'a mahlaseli a microwave, cesium carbonate e ka boela ea sebelisoa e le motheo oa ho lemoha karabelo ea esterification ea asiti ea benzoic le li-halogen tse tšehelitsoeng ka thata.
