Sigcina ubudlelwane obuhle nabathengi bethu, nangona kunjalo sihlaziya uluhlu lwethu lwezisombululo ngalo lonke ixesha ukuze sanelise iimfuno ezintsha kwaye silandele uphuhliso lwamva nje lwemarike eMalta. Sikulungele ukujongana neengxaki kwaye senze uphuculo ukuze siqonde onke amathuba kurhwebo lwamazwe ngamazwe.
I-Cesium carbonate yikhompawundi engaphiliyo. Yinto emhlophe eqinileyo kubushushu begumbi kunye noxinzelelo. Inyibilika kakhulu emanzini kwaye ifunxa umswakama ngokukhawuleza xa ibekwe emoyeni. Isisombululo samanzi se-cesium carbonate sinamandla e-alkaline kwaye sinokusabela kunye ne-asidi ukuvelisa ityuwa ye-cesium ehambelanayo kunye namanzi, kwaye ikhuphe i-carbon dioxide. I-Cesium carbonate kulula ukuyiguqula kwaye ingasetyenziswa njengomzekelo wezinye iityuwa ze-cesium. Isetyenziswa kakhulu kwiintlobo zetyuwa ye-cesium.

1. Iikhatalyst zokwenziwa kwezinto eziphilayo
1) I-Cesium carbonate C/N/O-arylation kunye neempendulo ze-alkylation: I-Cesium carbonate isebenza njengesiseko esomeleleyo sokukhuthaza iimpendulo zokutshintshwa kweeringi ze-aromatic okanye ii-heteroatom, njengokunyusa isivuno kwiimpendulo ezidibeneyo36.
2) Iimpendulo ze-cyclization: I-Cesium carbonate isetyenziselwa i-cyclization enamalungu amathandathu, i-intramolecular okanye i-intermolecular cyclization, kunye neempendulo ze-Horner-Emmons cyclization ukwenza lula ukwakhiwa kwee-molecules ezintsonkothileyo39.
3) Ukwenziwa kwe-quinazolinediones kunye ne-cyclic carbonates: I-Cesium carbonate ikhuthaza ukusabela kwe-2-aminobenzonitrile kunye ne-carbon dioxide ukuvelisa i-quinazolinediones, okanye idibanisa ii-cyclic carbonates ngokusebenzisa ii-halogenated alcohols kunye ne-carbon dioxide36.
2. Usetyenziso lwesayensi yezinto zokwakha
1) Izixhobo ze-elektroniki: I-Cesium carbonate isetyenziswa njengomaleko okhetha i-electron kwiidots ze-graphene quantum ukuphucula ukusebenza kakuhle kweeseli zelanga ze-polymer.
2) Ukulungiswa kwezinto ezisetyenziswa kwi-nanomaterials: I-Cesium carbonate ithatha inxaxheba ekuhlanganisweni kwezinto ezisebenzisa i-phosphorescent kunye ne-metal organic frameworks (MOFs) ukuze kuphuculwe iipropati zezinto.
3. Ezinye izicelo
1) Ukwenziwa kwezinto ezidityanisiweyo namayeza: I-Cesium carbonate isetyenziswa kumanyathelo abalulekileyo kwikhemistri yamayeza afana nokuxuba ii-phenols kunye nokulungiselela ii-phosphate esters.
2) Iimpendulo ezinobuhlobo nokusingqongileyo: I-Cesium carbonate ifikelela ekuguqulweni okusebenzayo kwaye inciphisa ungcoliseko ngaphandle kweentsimbi eziguqukayo okanye ii-catalysts ze-organic.
