    Application

    1. Zvizhinji zvezvinhu zve cesium carbonate mu organic synthesis inobva kune yakapfava Lewis acidity ye cesium ion, iyo inoita kuti inyungudika muzvinonyungudutsa zvinokonzerwa nedoro, DMF uye ether.

    2. Iyo yakanaka solubility muorganic solvents inogonesa cesium carbonate sechinhu chinoshanda inorganic base kutora chikamu mumakemikari reactions catalyzed ne palladium reagents akadai Heck, Suzuki uye Sonogashira reactions. Semuenzaniso, Suzuki cross-coupling reaction inogona kuwana goho re86% nerutsigiro rwecesium carbonate, nepo goho rekuita kwakafanana nekutora sodium carbonate kana triethylamine ingori 29% ne50%. Saizvozvo, muHeck reaction ye methacrylate uye chlorobenzene, cesium carbonate ine mabhenefiti ari pachena pane mamwe mabhesi einorganic, akadai se potassium carbonate, sodium acetate, triethylamine, uye potassium phosphate.

    3. Cesium carbonate inewo basa rinokosha zvikuru pakuona O-alkylation reaction ye phenol compounds.

    4. Ongororo dzinofungidzira kuti phenol O-alkylation reaction mune zvisiri-aqueous solvents inokonzerwa necesium carbonate inogona kunge yakasangana ne phenoloxy anions, saka iyo alkylation reaction inogonawo kuitika kune yakakwirira-chiitiko chechipiri halogens iyo inowanzoita kubvisa maitiro. .

    5. Cesium carbonate inewo kushandiswa kwakakosha mukugadzirwa kwezvinhu zvakasikwa. Semuyenzaniso, mukugadzirwa kweLipogrammistin-A komputa munhanho yakakosha yemhete-yekuvhara reaction, kushandiswa kwecesium carbonate senge inorganic base inogona kuwana yakavharwa-mhete zvigadzirwa zvine goho rakakura.

    6. Mukuwedzera, nekuda kwekunyungudika kwakanaka kwe cesium carbonate mu organic solvents, inewo kushandiswa kwakakosha mune yakasimba-inotsigirwa organic reactions. Semuyenzaniso, kuita kwezvikamu zvitatu zveaniline uye yakasimba-inotsigirwa halide inonyandurwa mumhepo yekabhoni dhaikisaidhi kuti igadzire macompounds ecarboxylate kana carbamate ane goho guru.

    7. Pasi pemwaranzi yemicrowave, cesium carbonate inogona zvakare kushandiswa senheyo yekuona esterification reaction ye benzoic acid uye yakasimba-inotsigirwa halogens.
