1. Ọtụtụ ihe onwunwe nkeceium carbonatena organic synthesis sitere na Lewis acidity dị nro nke cesium ion, nke na-eme ka ọ bụrụ ihe soluble na ihe ndị na-edozi ahụ dị ka mmanya, DMF na ether.

2. The ezi solubility na organic solvents na-enyere cesium carbonate dị ka irè inorganic isi isonye na chemical mmeghachi omume catalyzed site palladium reagents dị ka Heck, Suzuki na Sonogashira mmeghachi omume. Dịka ọmụmaatụ, mmeghachi omume njikọta nke Suzuki nwere ike nweta mkpụrụ nke 86% site na nkwado nke cesium carbonate, ebe mkpụrụ nke otu mmeghachi omume na ntinye nke sodium carbonate ma ọ bụ triethylamine bụ naanị 29% na 50%. N'otu aka ahụ, na mmeghachi omume Heck nke methacrylate na chlorobenzene, cesium carbonate nwere uru doro anya karịa ntọala inorganic ndị ọzọ, dị ka potassium carbonate, sodium acetate, triethylamine, na potassium phosphate.

3. Cesium carbonatenwekwara ngwa dị oke mkpa n'ịghọta mmeghachi omume O-alkylation nke ogige phenol.

4. Nnwale na-akọwapụta na mmeghachi omume phenol O-alkylation na ihe ndị na-adịghị mmiri mmiri na-akpata site na cesium carbonate nwere ike ịnweta phenoloxy anions, n'ihi ya, mmeghachi omume alkylation nwekwara ike ime maka halogens nke abụọ na-arụ ọrụ dị elu nke na-adịkarị mfe iwepụ mmeghachi omume. .

5. Cesium carbonatenwekwara mkpa ojiji na njikọ nke eke ngwaahịa. Dịka ọmụmaatụ, na njikọ nke Lipogrammistin-A compound na isi nzọụkwụ nke mmeghachi omume mmechi mgbanaka, iji cesium carbonate mee ihe dị ka ntọala inorganic nwere ike nweta ngwaahịa mgbanaka mechiri emechi nwere nnukwu mkpụrụ.

6. Tụkwasị na nke ahụ, n'ihi mma solubility nke cesium carbonate na organic solvents, ọ nwekwara ihe dị mkpa eji na-akwado organic mmeghachi omume siri ike. Dịka ọmụmaatụ, mmeghachi omume nke atọ nke aniline na halide na-akwado siri ike na-eme ka ikuku carbon dioxide na-emepụta ihe ndị na-emepụta carboxylate ma ọ bụ carbamate nwere nnukwu mkpụrụ.

7. N'okpuru radieshon microwave, a pụkwara iji cesium carbonate mee ihe dị ka ntọala iji ghọta mmeghachi omume esterification nke benzoic acid na halogens na-akwado siri ike.
