Isicelo

1. Iipropati ezininzi zecesium carbonatekwi-organic synthesis ivela kwi-Lewis acidity ethambileyo ye-cesium ion, eyenza ukuba inyibilike kwizinyibilikisi zezinto eziphilayo ezifana notywala, i-DMF kunye ne-ether.

2. I-solubility enhle kwi-solvents ye-organic yenza i-cesium carbonate njengesiseko esisebenzayo se-inorganic ukuba sithathe inxaxheba kwi-chemical reactions catalyzed by palladium reagents ezifana ne-Heck, i-Suzuki kunye ne-Sonogashira reactions. Ngokomzekelo, i-Suzuki cross-coupling reaction inokufikelela kwi-86% ngenkxaso ye-cesium carbonate, ngelixa isivuno sempendulo efanayo kunye nokuthatha inxaxheba kwe-sodium carbonate okanye i-triethylamine kuphela i-29% kunye ne-50%. Ngokufanayo, kwi-Heck reaction ye-methacrylate kunye ne-chlorobenzene, i-cesium carbonate ineenzuzo ezicacileyo ngaphezu kwezinye iziseko ze-inorganic, ezifana ne-potassium carbonate, i-acetate ye-sodium, i-triethylamine, kunye ne-potassium phosphate.

3. Cesium carbonatekwakhona unesicelo esibaluleke kakhulu ekuqondeni i-O-alkylation reaction of phenol compounds.

4. Iimvavanyo ziqikelela ukuba i-phenol O-alkylation reaction in non-aqueous solvents eyenziwa yi-cesium carbonate inokuthi ibe ne-phenoloxy anions, ngoko ke i-alkylation reaction inokuthi yenzeke kwi-high-activity second halogens ezixhomekeke ekuphenduleni ukuphelisa. .

5. Cesium carbonateikwanosetyenziso olubalulekileyo ekudityanisweni kweemveliso zendalo. Ngokomzekelo, kwi-synthesis ye-Lipogrammistin-A i-compound kwisinyathelo esiphambili sokuphendula kwindandatho yokuvala, ukusetyenziswa kwe-cesium carbonate njengesiseko se-inorganic kunokufumana iimveliso ezivaliweyo kunye nezivuno eziphezulu.

6. Ukongezelela, ngenxa ye-solubility enhle ye-cesium carbonate kwi-solvents ye-organic, nayo inokusetyenziswa okubalulekileyo kwi-solid-supported organic reactions. Ngokomzekelo, ukusabela kwamacandelo amathathu e-aniline kunye ne-halide eqinile-exhaswayo ifakwe kwi-carbon dioxide atmosphere ukuze idibanise i-carboxylate okanye i-carbamate compounds kunye nesivuno esiphezulu.

7. Ngaphantsi kwemitha ye-microwave, i-cesium carbonate isenokusetyenziswa njengesiseko ukuqaphela ukusabela kwe-esterification ye-benzoic acid kunye neehalogens ezixhaswa ngokuqinileyo.

Ugcino

ubushushu obuphantsi, indawo yokugcina umoya kunye neyomileyo
