ʻO Cesium carbonate 534-17-8 kumu kūʻai hana

Loaʻa ka nui o ka waihona, ke kūlana kiʻekiʻe a me ka hoʻouna wikiwiki. ʻOi aku ka nui me ka uku hoʻemi.
ʻO nā koi āpau, e hoʻokipa iā mākou i kēlā me kēia manawa.

Palapala noi

1. Nui na waiwai ocesium carbonatei loko o ka organic synthesis mai ka palupalu Lewis acidity o ka cesium ion, e hoʻoheheʻe ʻia i loko o nā mea hoʻoheheʻe organik e like me ka waiʻona, DMF a me ka etera.

2. ʻO ka solubility maikaʻi i loko o nā mea hoʻoheheʻe organik e hiki ai i ka cesium carbonate ma ke ʻano he kumu inorganic maikaʻi ke komo i nā hopena kemika i catalyzed e nā palladium reagents e like me Heck, Suzuki a me Sonogashira reactions. No ka laʻana, hiki i ka Suzuki cross-coupling reaction ke hoʻokō i kahi hua o 86% me ke kākoʻo o ka cesium carbonate, ʻoiai ka hopena o ka hopena like me ke komo ʻana o ka sodium carbonate a triethylamine wale nō 29% a me 50%. Pēlā nō, i ka hopena Heck o ka methacrylate a me ka chlorobenzene, ʻike ʻia ka cesium carbonate ma mua o nā kumu inorganic ʻē aʻe, e like me ka potassium carbonate, sodium acetate, triethylamine, a me ka potassium phosphate.

3. Cesium carbonateHe noi koʻikoʻi nō hoʻi i ka ʻike ʻana i ka pane ʻana o O-alkylation o nā pūhui phenol.

4. Manaʻo nā hoʻokolohua ʻo ka pane ʻana o ka phenol O-alkylation i loko o nā mea hoʻoheheʻe wai ʻole i hoʻokomo ʻia e ka cesium carbonate i ʻike paha i nā anion phenoloxy, no laila hiki ke hana ʻia ka hopena alkylation no nā halogens lua hana kiʻekiʻe i hiki ke hoʻopau ʻia. .

5. Cesium carbonateloaʻa nō hoʻi nā hoʻohana koʻikoʻi i ka synthesis o nā huahana kūlohelohe. No ka laʻana, i ka synthesis o Lipogrammistin-A pūhui i ka ʻanuʻu koʻikoʻi o ka hopena hoʻopaʻa apo, hiki i ka hoʻohana ʻana i ka cesium carbonate ma ke ʻano he kumu inorganic ke loaʻa nā huahana pani pani me nā hua kiʻekiʻe.

6. Eia kekahi, ma muli o ka hoʻoheheʻe maikaʻi ʻana o ka cesium carbonate i nā mea hoʻoheheʻe organik, he mea nui hoʻi ia e hoʻohana ai i nā hopena kūlohelohe i kākoʻo ʻia. No ka laʻana, hoʻokomo ʻia ka hopena ʻekolu o ka aniline a me ka halide paʻa i kākoʻo ʻia i loko o kahi ea carbon dioxide e synthesize i nā pūhui carboxylate a i ʻole carbamate me ka hua kiʻekiʻe.

7. Ma lalo o ka microwave radiation, hiki ke hoʻohana ʻia ka cesium carbonate ma ke ʻano he kumu e ʻike ai i ka hopena esterification o ka waikawa benzoic a me nā halogens kākoʻo paʻa.
