Cesium carbonate CAS 534-17-8
ʻO ka Cesium carbonate he mea hoʻohuihui ʻole. He paʻa keʻokeʻo ma ka lumi wela a me ke kaomi. Hiki ke hoʻoheheʻe ʻia i ka wai a hoʻopaʻa koke i ka makū ke kau ʻia i ka lewa. ʻO ka wai wai o ka cesium carbonate he alkaline ikaika a hiki ke hana me ka waikawa e hana i ka paʻakai cesium a me ka wai, a hoʻokuʻu i ke kalapona. He maʻalahi ka hoʻololi ʻana i ka cesium carbonate a hiki ke hoʻohana ʻia ma ke ʻano he precursor o nā paʻakai cesium ʻē aʻe. Hoʻohana nui ʻia ia i nā ʻano paʻakai cesium.

1. Nā mea hoʻoheheʻe hoʻohuihui organik
1) Cesium carbonate C/N/O-arylation a me alkylation reactions: Cesium carbonate he kumu ikaika no ka paipai 'ana i ka hoololi ana o na apo aromatic a i ole heteroatoms, e like me ka hoonui ana i ka hua ma ke kea-coupling reactions36.
2) Nā hopena Cyclization: Hoʻohana ʻia ka Cesium carbonate no ka cyclization ʻeono lālā, intramolecular a i ʻole intermolecular cyclization, a me Horner-Emmons cyclization reactions e hoʻomaʻamaʻa i ke kūkulu ʻana i nā molekala paʻakikī39.
3) Hoʻohui ʻia o nā quinazolinediones a me nā carbonate cyclic: Hoʻopili ka Cesium carbonate i ka hopena o ka 2-aminobenzonitrile me ke kalapona kalapona e hana ai i nā quinazolinediones, a i ʻole synthesizes cyclic carbonates ma o nā waiʻona halogenated a me carbon dioxide36.
2. Nā noi ʻepekema waiwai
1) Nā mea uila: Hoʻohana ʻia ka Cesium carbonate ma ke ʻano he papa koho electron i nā kiko kiko graphene e hoʻomaikaʻi i ka pono o nā cell solar polymer.
2) Ka hoʻomākaukau ʻana i nā nanomaterials: Ke komo nei ka Cesium carbonate i ka synthesis o nā mea phosphorescent a me nā metal organic frameworks (MOFs) e hoʻonui i nā waiwai waiwai.
3. Nā noi ʻē aʻe
1) Synthesis o nā lāʻau waena: Hoʻohana ʻia ka Cesium carbonate i nā ʻanuʻu koʻikoʻi o ke kemika lāʻau e like me ka alkylation o nā phenols a me ka hoʻomākaukau ʻana i nā esters phosphate.
2) Nā hopena pili kaiapuni: Loaʻa i ka Cesium carbonate ka hoʻololi maikaʻi ʻana a hōʻemi i ka pollution me ka ʻole o nā metala hoʻololi a i ʻole nā mea hoʻoheheʻe organik.
